Apple is making changes to the App Store in China following discussions with the Chinese regulator.

As of March 15, 2026, changes will be made to the commission rates that apply to the China mainland storefront of the App Store on iOS and iPadOS.

The commission rate for standard Apple In-App Purchase and paid app transactions will be 25%.

We strive for iOS and iPadOS to be the best app ecosystem and a great business opportunity for developers in China.

We are committed to terms that remain fair and transparent to all developers, and to always offering competitive App Store rates to developers distributing apps in China that are no higher than overall rates in other markets.

Updates to the Declared Age Range API are now available in beta for testing.

BrazilDevelopers who are distributing apps in Brazil can use the updated Declared Age Range API to obtain a user’s age category.

To assist with this, the Declared Age Range API—available on iOS, iPadOS, and macOS—provides developers with a helpful signal about a user's age.

Developers can use the Declared Age Range API to present significant update notifications to adults in these states through the Significant Update Action, now in beta.

When releasing a significant update, developers must follow the Human Interface Guidelines and provide users with a meaningful description of the update.

The beta versions of iOS 26.4, iPadOS 26.4, macOS 26.4, tvOS 26.4, visionOS 26.4, and watchOS 26.4 are now available.

Get your apps ready by confirming they work as expected on these releases.

And make sure to build and test with Xcode 26.4 beta to take advantage of the advancements in the latest SDKs.

TelemetryDeck is an app analytics service specifically for developers, designed to manage usage analytics that are anonymized, privacy-focused, and really easy to use.

Adopting Swift for backend servicesTelemetryDeck is built on Vapor, a web framework written in Swift, for building scalable APIs and services.

Under the hood, a Swift Vapor project is just a Swift Package with some dependencies.

Your Swift Vapor service is almost never the bottleneck.

Although profiling Swift code is easy, most slowdowns in a web service will arise from a combination of database, storage, and traffic load.

Welcome to this edition of “What’s New in Swift,” where we share interesting projects and updates in the Swift community that deserve visibility to a broader audience.

👋 I help grow and support the Swift open source community, and one of my favorite things has been increasing Swift’s participation in open source events.

FOSDEM may be over (for now), but I’m already excited about how the Swift community will show up next year!

Vladimir Kukushkin works on foundational Swift server libraries at Apple, and is a maintainer of Swift System Metrics.

We are excited to announce the 1.0 release of Swift System Metrics, a Swift package that collects process-level system metrics like CPU utilization time and memory usage.

Swift System Metrics is part of a larger set of packages that provide an end-to-end solution for integrating metrics into your Swift applications and services.

Once system metrics are collected, they’re reported to Swift Metrics, a backend-agnostic metrics API that can work with popular backends like Prometheus and OpenTelemetry.

For this edition of “What’s new in Swift,” we invited a developer to share their experience:Hi, I’m Nick Sloan.

We chose Swift for Studioworks because of how easy it is to write safe and reliable code with great performance.

Our Swift project makes use of Hummingbird 2, Soto (for its incredible DynamoDB Codable support), Hummingbird MacroRouting, and Elementary.

We’ve been deploying web applications with PHP and Python for decades, and getting started with a Swift web project was certainly a bit slower.

Swift on the web has been a resounding success for us, and I hope we’ll see this part of the community continue to grow!

We are excited to announce the creation of the Windows workgroup!

The new Windows workgroup joins a growing list of Swift workgroups, including the Android workgroup, Build and Packaging workgroup, and Testing workgroup which were all added in the past year.

The workgroup will build upon these efforts and focus on work to:Improve and maintain Windows support for the official Swift distribution.

Identify and recommend best practices for bridging between Swift and the Windows API, and for shipping Swift libraries with Windows applications.

Learn more about the Windows workgroup by reading its charter.

While one could go and rewrite these libraries in Swift, usually there is no need, because Swift provides direct interoperability with C. With a little setup, you can directly use existing C libraries from your Swift code.

In this post, I’m going to use these annotations to improve how Swift interacts with the WebGPU C code.

You can create a module map for the WebGPU header by writing the following to a file module.modulemap :module WebGPU { header "webgpu.h" export * }The easiest thing to do is to put module.modulemap alongside the header itself.

The resulting API notes are in WebGPU.apinotes, and the generated Swift interface after these API notes are applied is here.

I have a solid utility app with a great free-to-paid conversion rate. But whenever I try to run paid ads to scale past organic App Store searches, the CPI is so astronomically high that it takes almost 8 months just to break even on a single user. For devs running profitable independent apps: Is paid acquisition mathematically dead for monthly subscriptions, or is there a specific funnel trick to force front-end profitability? submitted by /u/Adept_Psychology_654 [link] [comments]

Hey guys. I’m very new, slowly dipping my toes into it. I wanted to ask what is the best approach to make a 2D die rolling app with animations like spinning or sparkles and what not. Xcode seemed a bit limiting from what I have gathered. I’m fine with just presenting me with keywords to search or programs to learn. TYSM! submitted by /u/Dry_Business_2053 [link] [comments]

I made an API that returns Apple keyword popularity scores (5-100), difficulty ratings, top apps, and related searches. Runs on Apify, there is no monthly fee and Apify's free plan covers ~250 keywords/month. Supports 57 storefronts. Has REST API + Python/JS clients for automation. This won't replace a full ASO suite if you need historical trends or competitor monitoring. But if you want raw keyword data without a subscription, it does the job for a fraction of the cost. What you get per keyword: Popularity score (5-100) - real Apple data, not estimated Difficulty score (0-100) - based on competition strength of top ranking apps, calibrated against pro ASO tools (r=0.87, ~6.5pt mean error) …

Lucky Cat adds a button to your dashboard that gives you accurate, up-to-date forecasts for your current month and full-year revenue. I was also able to geek out on the calculations. It uses a dynamic weighted average based on the date, and adjusts its weight between recent daily averages, month-over-month growth, and year-over-year growth. It reads historical data and calculates everything locally in your browser, so your financial data is completely private and secure—it never leaves your machine…

Just shipped Stickly - an AI sticker maker for iOS. Wanted to share the technical decisions because some of them surprised me. The stack: - SwiftUI end-to-end (no UIKit fallbacks, iOS 17+) - Replicate API for image generation — SDXL-based, called directly from a Firebase Cloud Function so I'm not exposing the API key client-side - Gemini for prompt preprocessing — takes whatever the user types and converts it into a proper generation prompt. This was a game changer. Users type "a cool dragon" and Gemini turns it into something the diffusion model actually handles well - Firebase for auth + Firestore for user packs + Storage for generated images - RevenueCat for subscriptions (never doing ma…

Stripe atlas was easy for my other startup - and useful since we were going to use Stripe for the B2B payments and it was a web app. We also used Stable since I had cofounders and we wanted a virtual address - which made Stripe more affordable because they get 40% off via Stable. BUT for solo devs - and iOS ones especially - Stripe is not needed (if using IAPs), and a virtual address isn't totally needed? So not sure if Stripe Atlas is worth the $500.

Yes, it might help with a simple task, but does it do everything that everyone in that company used the SaaS product for?

What I talked about last week in terms of detailed thought going into the prompt isn’t just for code.

It’s much more about thinking through edge cases, user interfaces, features, and everything else that goes into making good software.

So I kept on making the software that I wanted to build, that I wanted to exist in this world.

I’ve linked to several workflows like this for iOS, but don’t think I have linked to one for macOS before!

Well, yes, but not on how to set it up, use it, or whether I like the Xcode 26.3 implementation.

It’s good, and the presenters do a good job of explaining it, but you’ll notice something about the prompts they use.

I’d love to see the spec in a completely separate context window to the coding agent, too.

I’d love to see Apple and the Xcode team really lead from the front and reduce the friction of working this way.

Issue 742 6th February 2026 Written by Dave VerwerI received plenty of feedback on my comment from last week about Swift for Wasm and Windows, and wanted to start this week by highlighting the projects that I heard about.

They are even hiring for a couple of roles (1, 2), if you’re interested in using Swift and Wasm together every day.

Also on the Wasm side, Geoff Pado’s Barcode Generator for his Barc app uses Wasm to generate the barcode images.

What I didn’t realise is that much of that Electron app is backed by Swift code.

😂What’s potentially even more exciting than the built-in agent support in Xcode 26.3 is what Rudrank Riyam discovered by digging a little deeper into the release.

Issue 741 30th January 2026 Written by Dave VerwerA couple of announcements combined to inspire this week’s comment.

I’m not aware of any current and significant Wasm projects built with Swift¹, and even if I missed some, the ecosystem would certainly benefit from more!

That said, I’m delighted to see a real-world open source project that is pushing Wasm into real use-cases.

Issue 739 16th January 2026 Written by Dave VerwerIf you’ve spent any time at all reading about AI coding agents, you’ll likely have heard that people get better results when working with languages other than Swift.

In fact, I’ve seen people say that type-safe languages produce better results as the agent can rely on the compiler to automatically catch basic errors.

So I’ve been interested to receive several recommendations of a tool that really helps the agents get to grips with the current state of Swift.

I can’t imagine a better guide to getting everything correct than the one in Alberto De Bortoli’s latest blog post.

Issue 738 9th January 2026 Written by Dave VerwerIt happened while I was away on my end-of-year break, but at the end of last year Apple announced changes to iOS in Japan.

iOS 26.2 enabled the changes, and now there are several regions of the world where users could be using browsers with non-WebKit rendering engines.

At the time it felt like we had a chance for HTML rendering engines to converge into one standard implementation (apologies to Gecko 😬), which promised to be a win for the web.

Note, I’m not talking about browsers, strictly about rendering engines.

One year ago, iOS 18 was at ~78%.

Issue 737 19th December 2025 Written by Dave VerwerI’m back from my vacation, which was exactly what I needed, and I now find myself writing the last issue of 2025!

😱To mark the end of the year, Apple announced this year’s App Store Award winners!

You can see the full list of awards and winners on the developer site, although I actually prefer their press release writeup as it includes screenshots of the apps.

I especially liked the Be My Eyes app, which restored some of my faith in humanity.

Follow along and have some Swifty fun with that Pi that is still sitting in its box on your shelf.

It takes the idea of using LLMs inside an app one step further than having the model return text or structured data.

I’d recommend watching this 30-second slice of the video for a better explanation than I can manage in a few words.

It includes a built-in set of widgets for common UI, and you can add your own too.

It has been possible to get Swift apps running on really tiny devices for a while now (as mentioned in Issue 655, Issue 673, and Issue 691), although getting it going was not trivial.

Issue 735 14th November 2025 Written by Dave VerwerIt’s been a few years since the closure of the Swift Weekly Brief newsletter.

It regularly covered detailed information on Swift Evolution proposals, topics from the Swift Forums, and other Swift community news.

I cover Swift news, of course, but I mainly stick to the larger announcements rather than covering anything still going through the Swift Evolution process.

Issue 734 7th November 2025 Written by Dave VerwerI did not have Apple launching a web-based version of the App Store on my bingo card for this week, but here we are.

It’s a full, multi-region implementation of the App Store, with the “Today” view (including featured lists and events) and Apple Arcade.

Should you rely on linking directly to an App Store listing, assuming that everyone who clicks on it will have a device that will launch the store and show your product page?

You also get the chance to let people opt in to receiving email, either as customers or as potential customers before they make an App Store download.

It’s a nice step forward for the App Store!

🎃The first time I ever wrote about Swift running on Android was back in Issue 220 when I linked to Romain Goyet’s post.

NewsApple may have already announced this:Offer codes build on the functionality of promo codes and provide improved configuration and customer eligibility options.

As a result, starting March 26, 2026, you’ll no longer be able to create promo codes for In-App Purchases in App Store Connect.

Issue 731 17th October 2025 Written by Dave VerwerThere has been plenty of criticism of Liquid Glass, both during the beta and since its official release.

There’s no question that Liquid Glass is a step back for legibility.

Michael Tsai, as always, has put together a great round-up of Liquid Glass comments from social media.

Maybe the most interesting thing about Liquid Glass is the conversations and critique that it has sparked.

As of this morning, however, CBS Sports is the top downloaded app on the App Store.

Prior to March Madness and sports apps defeating AI, the top three chatbot apps briefly competed with a hamburger promotion.

Amazon is offering the 13-inch M4 MacBook Air with 24GB of RAM and 512GB of storage down at $1,199 shipped.

Amazon is now offering the 13-inch 128GB M4 iPad Air that just launched starting down at $735.49 shipped.

This is slightly below the initial launch week discount and the best deal we have tracked yet on the most affordable 13-inch variant.

Look at the return of $200 price drops on Apple’s banger 2TB 13-inch M5 iPad Pro.

Amazon is now offering the 2TB 13-inch M5 iPad Pro down at $2,099 shipped in Space Black and $2,094 in silver.

In an interview with Good Morning America's Michael Strahan this week, Apple's CEO Tim Cook said he is "not a political person."

Strahan said Cook has been criticized over his relationship with U.S. President Donald Trump.

Cook reportedly also personally donated $1 million to Trump's second inauguration fund.

"I'm not a political person on either side," he added.

Amazon's Alexa+ AI assistant is rolling out to all Amazon customers in the United Kingdom beginning today as part of an early access program.

Customers who purchase a new eligible Echo device in the U.K. will be granted Early Access, while customers who already have a compatible device can register to receive an invite.

Alexa+ works on the majority of Echo devices, compatible Fire TV devices, and the Alexa app, with web browser support coming soon.

The service is available at no additional cost during the early access period, though Amazon hasn't said how long it will last.

Whenever it does end, Alexa+ will cost £19.99 per month, or come free with an Amazon Prime membership.

Apple launched AppleCare One in the U.S. in July 2025.

The plan starts at $19.99 per month and covers up to three products, with additional devices available for $5.99 per month each.

It includes all the same benefits as AppleCare+, such as unlimited accident repairs, priority support, and battery coverage.

AppleCare One also brought theft and loss protection to the iPad and Apple Watch for the first time.

On its own, the EUIPO filing isn't confirmation of a launch date for EU markets, but trademark registrations of the sort have typically preceded expanded rollouts of Apple services.

In an interview with Nikias Molina at New York's Grand Central Terminal last week, Apple's CEO Tim Cook briefly commented on the future of the iPhone.

"There's so much left that we can do with the iPhone," said Cook.

Cook said iPhone demand during the quarter was "simply staggering."

"iPhone had its best-ever quarter driven by unprecedented demand, with all-time records across every geographic segment," said Cook, in January.

It remains to be seen if there is ever a device that supplants the iPhone, and smartphones in general, but Cook is certainly not worried right now.

tvOS 26.4 includes a new Genius Browse section in the Apple TV app, which gives recommendations for TV shows and movies across multiple suggested categories.

When browsing through the suggested movies and TV shows, tvOS 26.4 also provides titles related to the one that's highlighted.

Genius Browse suggestions are not static and will continually show new content categories.

The content that Apple suggests is not limited to shows and movies on the ‌Apple TV‌ service, though those are included.

We're expecting tvOS 26.4 to be released as soon as next week.

Perplexity today expanded its Comet browser to iOS, making its AI Comet Assistant available to iPhone users.

The Comet browser for iOS has many of the same features as the Comet browser for the desktop, including a voice mode for speaking questions and a hybrid search experience, but it does lack extensions.

Comet offers standard search results like you might expect from any web search, but the added Comet Assistant is able to provide more in-depth answers and complete tasks.

The Comet Assistant can also complete web-based tasks, like summarizing emails, searching for products, comparing prices across websites, and more.

Perplexity does collect browsing and search history from Comet to crea…

Each adult member of the family can now use their own payment method for purchases, rather than being forced to share a payment method.

The shared payment restriction is changing in iOS 26.4, and now Family Sharing members can share their content without having to share a payment method.

The family organizer pays for everyone's purchases unless they turn off Purchase Sharing or other adult family members use their own payment method to make purchases.

Other adults in a Family Sharing group can still opt to use the organizer's payment method, but they can also input a separate payment method.

Family Sharing accounts for children will continue to use the organizer's payment method for any pur…

The iOS 26.4 update that Apple plans to release as soon as next week includes improvements for the built-in iOS keyboard.

In its notes for the software, Apple says iOS 26.4 offers "improved keyboard accuracy when typing quickly."

It's not entirely clear what Apple means by improved keyboard accuracy, but it's likely a fix for an iOS keyboard bug that was highlighted on YouTube late last year.

It sounds like iOS 26.4 addresses the root issue, preventing the keyboard from inserting the wrong letter when the user is typing quickly.

If you've experienced issues with the iOS keyboard that have been fixed in iOS 26.4, let us know in the comments below.

Apple is finally fixing one of Family Sharing's most awkward limitations in iOS 26.4, letting multiple adults on one family pay for their own purchases without breaking shared access.Apple updates payments for Family SharingFor years, Family Sharing forced everyone into a single payment method whenever purchase sharing was enabled. The approach worked for traditional households, but it created friction for anyone sharing with friends, partners, or extended family.One person effectively became the default payer, even when it made no practical sense. iOS 26.4 changes the structure by letting adult members use their own payment methods while still joining shared purchases.

Like all good engineering solutions, building a design system should aim to solve an actual problem that we’re facing within a given project.

In the case of Genius Scan, since our initial focus was on lists, we started by creating a basic Row component, which would simply combine a leading and trailing element into a horizontal row:public struct Row: View { public var leading: Leading public var trailing: Trailing public init ( @ViewBuilder leading: () -> Leading , @ViewBuilder trailing: () -> Trailing = EmptyView .

leading = leading () self .

Configuration () ... } extension EnvironmentValues { @Entry var configuration = Configuration () }Note how we also define an @Entry for our configu…

Let’s say that we’ve declared a User struct within a project, which currently only contains constant let properties:struct User: Identifiable , Codable { let id: UUID let name: String let bio: String let imageURL: URL ? }

That could be done like this:struct User: Identifiable , Codable { let id: UUID let name: String let bio: String let imageURL: URL ?

init (id: UUID = UUID () , name: String , bio: String , imageURL: URL ?

id = id self .

Such an API could take the form of a UserTransformer protocol, which uses Swift’s inout parameter feature to enable each transformer to directly mutate the User value that was passed to it, without first having to make a mutable copy:protocol UserTran…

However, sometimes we might be working with a type that requires some additional data that’s not present in the JSON (or whichever data format we’re decoding from) in order to be initialized.

ID ) async throws -> User { let favoritesURL = favoritesURLForUser (withID: id) let userURL = urlForUser (withID: id) async let favorites = request (favoritesURL) as Favorites async let partialUser = request (userURL) as User .

membershipPoints , favorites: favorites ) } ... private func request( _ url: URL ) async throws -> T { let (data, _ ) = try await session.

userInfo [configurationUserInfoKey] wrapped = try Wrapped ( from: decoder, configuration: configuration as !

func decode( from data: Dat…

For example, let’s say that we’re building a custom Container view, which renders a header on top of a content view, while also applying some default styling to those two components:struct Container: View { var header: Header var content: Content var body: some View { VStack (spacing: 0 ) { header .

var body: some View { Container (header: { Text ( "Welcome" ) }, content: { if let user { HomeView (user: user) } else { LoginView (user: $user ) } }) } }Neat!

init , content: content) } }Note that we have to use a closure for our content property above, rather than just a Content value.

init , @ViewBuilder content: () -> Content ) { self .

header = header () self .

We’ll look at how to install and use these agent skills in Xcode, Claude Code, Codex, Gemini, and more.

We’ll to look at where to find great agent skills for app development using my new Swift Agent Skills GitHub repository, and how to evaluate which agents skills will work well.

Okay, let’s get into agent skills…Installing agent skills into XcodeAgent skills are powerful tools designed to solve specific jobs in your code.

Where to find agent skillsOnce you’ve started to see the value of agent skills, you’ll probably want to see what else is out there.

Anyway, that’s it for agent skills and agent files.

If you’re writing SwiftUI with AI coding agents like Claude Code, Codex, or Gemini, I’ve written an open-source SwiftUI agent skill that helps identify and fix common mistakes they make when writing SwiftUI – things like modern API usage, performance, accessibility, and more.

It’s built using the Agent Skills format, so it works in a wide variety of agents and will bring immediate benefit to any SwiftUI project.

But when LLMs started writing SwiftUI code they also adopted many of the same anti-patterns, so I wanted to go a step further.

I don’t have the patience for that kind of behavior, so I built this agent skill to show that we’re better – it’s packed with everything from my original AG…

In this tutorial, you’ll learn the basics of app observability, and understand how your app behaves in the hands of your customers.

Integrate Open-Telemetry Framework to your iOS app.

You can learn more about App observability from the App Observability Module.

You’ll create a singleton instance of the class you created OTelSpans and you’ll use the shared instance across the project.

Add this method:public class func createSpan( scopeName: String, name: String ) -> (any Span) { shared.createSpan( scopeName: scopeName, name: name) }

Well, it’s getting model inheritance at least!

Let’s say you have a generic recipe class that you have setup for SwiftData already.

This year at WWDC, SwiftData was updated to allow for model inheritance when constructing your SwiftData types.

This feature is only available in iOS 26 and above, so any uses of this new API have to be annotated with an @available check:@available(iOS 26, *)This unfortunately means that if your minimum target is earlier than iOS 26, you won’t able to use model inheritance – so plan accordingly!

If using model inheritance is important to your program structure, you will need everyone to upgrade to iOS 26 (or above) before using the next version of your app.

In this tutorial you’ll go through some of the scenarios you may encounter when upgrading an iOS App to use Liquid Glass.

Liquid Glass is Apple’s attempt to convey their belief that Hardware and Software should be closely entwined.

Getting Started with Liquid GlassBuilding an app for iOS 26 requires a minimum of Xcode 26 to use.

You learned about how Liquid Glass differs to the minimalist design Apple previously relied on and also how easy it is to adopt Liquid Glass into your app.

To continue learning about Liquid Glass, take a look at the Liquid Glass module in the What’s New in iOS 26 Program.

In this tutorial, you’ll modify an app to use Apple Foundation Models to summarize text.

Apple Foundation Model RequirementsTo use the on-device language model, the user needs to have hardware that supports Apple Intelligence.

Even if the Simulator is running an appropriate version of the OS, it will only work if the underlying macOS supports Apple Foundation Models.

When following along with this tutorial, also note that macOS 26 virtual machines often fail to support Apple Foundation Models.

Before using Apple Foundation Models, you must ensure the user’s device supports it and that the user has turned it on.

Build your own low-level game engine in Metal!

Metal is a unified application programming interface (API) for the graphics processing unit, or GPU.

Finally, Metal is a low-overhead API because it reduces the central processing unit (CPU) cost by multi-threading and pre-compiling of resources.

This book will introduce you to low-level graphics programming in Metal — Apple’s framework for programming on the graphics processing unit (GPU).

Because you’ll have built your 3D game engine from scratch, you’ll be able to customize every aspect of what you see on your screen.

If you’re on a such a file system and change the case of a filename, Git will not record the new name — unless you use git mv to perform the renaming.

git mv stages the rename but not the editsGit has the promisingly named git mv command, but since Git doesn’t track renames, git mv is mostly no different than doing the renaming in some other way and then staging the change (the deleted and newly created file).

echo "Usage: $0 " exit 1 fi old = " $2 " new = " $1 " # Situation: we renamed $old to $new.

`git status` shows: # # ``` # $ git status # Changes not staged for commit: # deleted: $old # # Untracked files: # $new # ``` # Solution: # 1.

Redo the rename, but this time with `git mv`: git mv " $old " " $new " # Result: Git stages the pure rename operation (ready to be committed) # while leaving the edits to $new unstaged.

I wrote this in response:Both Apple and Phil Schiller himself took a huge risk in doing this.

And humanizing the company and its decisions, especially to developers — remember, developer relations is all under Phil — might be worth the PR risk.

* * *For unspecified reasons, Apple has declined to participate this year, ending what had become a beloved tradition in our community — and I can’t help but suspect that it won’t come back.

We’ll see what their WWDC PR strategy looks like in a couple of weeks.

Xcode 26.3 is already out, and I only recently stumbled upon an article about a new build flag in Xcode 26: COMPILATION_CACHE_ENABLE_CACHING.

We’re no longer at “it writes boilerplate for me.” We’re at “it writes the code, runs it, taps the UI, and checks whether it actually works.”Three tools that make this very real:• AXe — a CLI to control iOS Simulator via accessibility & HID functionality.Tap at specific coordinates. Swipe with precise velocity. Type text. Dump the accessibility tree. Record video. Chain it in scripts.• MotionEyes — analyzes UI motion frame-by-frame.It can detect when pixels start changing and when they stop — so you can a…

Xcode 26.3 ships agentic coding.The AI now has real tools: filesystem access, project config changes, builds, tests, previews. At this rate, Xcode might eventually evolve into a full IDE. (not guaranteed)Thanks to MCP, Xcode can be used as a headless IDE backend: connect it to your agent, stay in the terminal, and let Xcode do the “IDE stuff” for you. Except it currently asks for permission on basically every action, doesn’t allow project-level agent trust, and refuses to render SwiftUI previews unless the editor tab is open. 😥So close. So very Apple.#Xcode #AI

TIL: UIScreenShotServiceDelegate exists since iOS 13. Found it only today. Somehow missed it for years.It lets your app provide a custom Full Page representation — basically a PDF that the system uses when the user chooses that mode. Safari uses it for long pages. Apple Maps uses it to export a clean map, without UI chrome.Feels like one of those UIKit features that quietly shipped and never got attention.

Probably everyone is already tired of reading about Clawdbot. Too many posts, too much noise.But this story is on a different level. Honestly, it reads like a Netflix script.The short version:• Anthropic complained about the Clawdbot name.• The project rushed a rename.• During that window, the account was taken over.• Under the old name, fake tokens were pushed to the market.• Within hours, FOMO kicked in on Solana and the token briefly hit a ~$16M market cap. 🫠Not a bug — pure timing.https://dev.to/sivarampg/from-clawdbot-to-moltbot-how-a-cd-crypto-scammers-and-10-seconds-of-chaos-took-down-the-4eck#security #Clawdbot

As multi-module setups become more common, it helps to be precise about how imports work.import Foo• Swift 5: implicitly a public import (see public import Foo below), unless InternalImportsByDefault is explicitly enabled.• Swift 6: a regular internal import — visible only inside the module and does not affect the public interface.public import Foo• Allows Foo types to be used in public / open API.• Downstream modules gain access to Foo, but still have to explicitly write import Foo themselves.@_exported import Foo• Foo types become automatically available to any module importing yours.• Useful for facade modules.https://alexanderweiss.dev/blog/2026-01-16-exported-import-vs-public-import#sw…

Every time Apple ships a “simpler” sync API, I hope this is the one where I won’t have to think too much. CKSyncEngine almost looks like it… until you read Christian Selig’s article.It’s not a tutorial — it’s a list of things that will quietly break later if you trust the magic:• saves resolve conflicts, deletes don’t;• enums in synced models are a trap;• engine state must be persisted;• quota errors are still your problem.The API is better, but architectural responsibility didn’t go anywhere. So it’s worth reading if you’re considering CKSyncEngine.https://christianselig.com/2026/01/cksyncengine/#iOS #CloudKit

Every time I read articles about SF Symbols, I’m amazed by the animations, the customization, and how polished everything looks. I think: maybe next year I’ll finally sneak them into a real app…Spoiler: yeah… probably never. Most of these ideas live happily in pet projects and playgrounds.Maybe there are some lucky people in this chat actually using them in production? If so — envy! As the year ends, here’s my little wish for all of us: may next year finally give us a project brave enough to let us play with them for real! 😎https://nilcoalescing.com/blog/AnimatingSFSymbolsInSwiftUI/#SwiftUI #animations

Recently had to animate a SwiftUI sheet resizing itself — sounds like a super basic thing, but the actual solution was anything but obvious.If you ever need an animatable, auto-sized sheet, this write-up breaks down an approach. Might save you a couple of hours (and some sanity).https://clive819.github.io/posts/animatable-auto-sized-to-fit-swiftui-sheet/#SwiftUI #Layout

Nice reminder about how .task behaves when it depends on a property that can change — and why adding an id makes all the difference.https://chris.eidhof.nl/post/swiftui-task-identity/#SwiftUI

Apple quietly dropped a few nice App Store updates.The biggest one — you can finally submit a new version, while another build is still under review. 🙌Other small but welcome changes:• Up to 70 custom product pages per app (each with unique keywords).• Offer codes now work for all IAP types, replacing old promo codes by March 2026.https://www.macrumors.com/2025/10/29/apple-developer-app-store-updates/#AppStore
