@TOPRE_REALFORCE Any plan to release the R4 for Mac?

Continuations are incredibly useful when you're bridging callbacks to async/await. They offer you a way to to make unstructured, possibly non-Swift Concurrency related work appear structured.

At the WWDC26 Platforms State of the Union developer keynote, we mentioned that the TrueType font hinting engine had been rewritten in Swift, for speed and memory safety. This article goes into considerable detail on "what" and "how": https://t.co/HmAeSp7gw9

Is there a way to turn off all the AI stuff in Xcode 27?

On a serious note, the last the time we had Design Principles in the HIG was much too long ago.

With the help of the Apple design team they are back and completely refreshed.

Please take a moment with them. We’re in an era where the responsibility of being a designer is more important than ever and hope these principles help guide you as much as they guide us.

By 2027 Dario will claim it's too dangerous to have humans hand produce code

And guess who's product is selling the shovel?

One of the most common concurrency warnings in SwiftUI is “Publishing changes from background threads is not allowed”. This happens when you update a UI property from a non-main thread.

It’s easy to fix: just find the function which updates the property, and mark it @MainActor. Alternatively, simply wrap the update inside a call to await https://t.co/OE5tUAYKlT { }.

If you don't want to deal with this at all, just use the new Swift 6.2 approachable concurrency to isolate your code to the main actor by default.

AI agents that learn from each other without ever talking to each other.
and
Every agent today accumulates knowledge: conversation history, user preferences, and research notes. That memory is what makes an agent useful.

But the moment you have more than one agent, memory becomes a distributed systems problem.

We built a simple solution based on block-level LWW.

@Jaenam97 @framer @XorDev thank you so much! 💕

SwiftUI Tip 💡

In iOS 26.1+, tabViewBottomAccessory() has a new overload that lets you conditionally show the TabView’s bottom accessory.

Useful when the accessory should appear only when needed.

Published a new YouTube video covering some advanced techniques for working with Optionals in Swift. I shared these as part of my presentation "Swift's Hidden Gems" at the @ARCTIConference and many developers were surprised.

Make your views and controls fit perfectly within their containers using new SwiftUI APIs in iOS 26 such as the ConcentricRectangle shape and the containerShape() view modifier: https://t.co/Q7b6MjxtXJ

@natpanferova Congrats Natalia!

[Natalia Panferova @natpanferova]

My new SwiftUI book is finally out 🎉

I wrote "The SwiftUI Way" for developers who feel like they are fighting the framework as projects grow in complexity. It will help you align your code with SwiftUI's internal expectations to avoid common pitfalls.

SwiftUI has a hidden CAHostingLayer API — host your SwiftUI views directly in a CALayer.
Currently used internally by UIKit/AppKit and WebKit. Available since iOS 18 / macOS 15.
I wrote a guide on how to access it without Apple's internal SDK 👇

@BasicAppleGuy What a semi translucent keycaps like the old glory Pismo? 😁

[Oskar Groth @oskargroth]

@sids7 Connect to Hopper MCP and it’s basically as good as having access to all of Apple’s internal source code

Precisely scope animations to specific animatable attributes in SwiftUI by using the animation(_:body:) API introduced in iOS 17: https://t.co/PzwAflM3mO
