I think non-global actor isolation capture is buggy. I made some tests and saw assertIsolated() failing after checking the #isolation was correct and even the queue I use as executor. There may be some GCD issues like assumeIsolated that was buggy on macOS < 15. Also #isolation may be wrongly set.

I have an almost same pattern w/ WebSocket server actor + WS client actors. Clients are created via a factory. I tried to pass a cancel handler isolated to the server and was never able to make it work w/out data-race. I Relied on a global actor but ended up passing a weak server instance.

Design Resources for Mac Resources for designing great Mac apps that follow common desktop patterns using native views and controls.

I haven’t completed it but I have started modernizing the Apple Mac HIGs here. I have topics on toolbar guidelines and layout guidelines that are detailed, illustrated, and modernized.

iOS 26 is ugly but as far as I experienced pretty stable. And recent changes made is readable too. But I just can’t w/ macOS 26… this sidebar design alone is an insult to whoever invented the sidebar…

Does someone also sees SwiftUI lists not working properly (unable to select item) on MacOS 14 for apps compiled under Xcode 26 ?

I won’t argue on the AI part. But yeah I don’t see Apple gatekeeping everything too. Thank you for sharing your view πŸ˜ƒ

Thank you for the explanation! If we put aside app stores I’m worried about access to the platform as a whole. I write code that runs 24/7 on Mac and nobody will ever install it through any store, I do iOS tooling too. I wonder if at some point I’ll be barred from the tools / signing system, …

Interested to know more. Also since we both dev on Apple platforms should we be worried as they’re IS tech also ?

Never thought about using AnyCancellable for tasks. Great idea thank you for sharing!
I think you made a mistake in the first code example featuring setup, you use the store method on the task before introducing it when should have used it on the publisher.

I have trouble reading the comments and method/func names. Not enough contrast I think. But overall I like it πŸ˜ƒ.

I never update until the x.2, earlier if stability and app availability are a consensus. But here I know I’ll wait for a backlash and a potential redesign and I know they won’t… πŸ˜•

Not a fan of iPadOS and iOS 26 but I feel that something I could acclimate to. But macOS ? An insult…

Would be great if you hadn’t to backstick them at call site. Like you do w/ keyword used as variable names (var `for` = 4)

@ FocusState and the focus modifier. But it’s way more limited than messing w/ the first responder directly.

Exactly ! This nuance is important and shows how rare the need of global actors really is.

20.07.2025 07:19 β€” πŸ‘ 2    πŸ” 0    πŸ’¬ 0    πŸ“Œ 0

It’s really about coordinating concurrent accesses to a unique ressource. Say a database client, writing to a single log file, etc… Global actors allow you to make this a simple decoration in your code while doing all the heavy lifting. And it’s clearly and solely about isolation.

In the early days of SwiftUI I remember asking myself β€œis that buggy or do I still dont get the thing” a lot ! Now it’s better, on both sides.

Congrats ! I'd be interested to know what technique you use to generate the beat. Simple timer or something else ? I'm about to start working on a tool where I need a precise beat and I'm not sure how to do it the right way. So far I used AsyncStream + Task.sleep when needed...
