Spoke too soon var body: some Scene { WindowGroup { AppView(store: store) .onContinueUserActivity(NSUserActivityTypeBrowsingWeb) { userActivity in // handle it here } } } This will duplicate my current window. So now from one window I end up with 2 and 3 and so on.

I'v been writing an app for macOS for years. I'm not aware my app cares about devices. It should not, it only cares about full disk access. So how does the Mac figure out that my app needs access to Devices. I want to pre-fill this when I build the app so my customers do not freak out.

It seems the swift team is tightening the screws on concurrency, but ... The error is: Main actor-isolated property 'buttonMaxWidth' can not be mutated from a Sendable closure Where: @State private var buttonMaxWidth: CGFloat = 120 Now looking under the hood: @preconcurrency @inlinable nonisolated public func onPreferenceChange<K>(_ key: K.Type = K.self, perform action: @escaping @Sendable (K.Value) -> Void) -> some View where K : PreferenceKey, K.Value : Equatable but, I wonder why they did not mark this func as @MainActor isolated? I suspect the 2m lines behind that would have to be refactored. for now my solution 1 is to assume .onPreferenceChange(ButtonWidthPreferenceKey.self) { newSize in MainActor.assumeIsolated { buttonMaxWidth = newSize } } What's the point of all these rules if we can say ignore the rules in one line ? For solution 2, you can be more pedantic and declare a MainActor isolated func that you can than open a Task that calls it, too much work ... .onPreferenceChange(ButtonWidthPreferenceKey.self) { newSize in Task { @MainActor in setButtonMaxWidth(newSize) } }

Woha, just upgraded my Mac to Sequoia and noticed this beauty. So basically .frame(minWidth, idealWidth, maxWidth) just became useless when my view is displayed in a .sheet Shouldn't y'apple folks infer that? If I did call .frame than make the view resizableSheet, otherwise display it at intrinsic size as it happens now. ... Thank you for the solution.

year 2025 and same issue, latest Mac and os, Sequoia

Went on the iPhone app and it accepted my renewal. Not sure why the web app is refusing payments. Most likely a temporary glitch.

This issue is back with vengeance on Tahoe 26.2, Xcode 26.2 I basically throw a sheet that depending on state might transition from view1, view2 and maybe view3 The sheet grabs the size of the first view that it renders, and when I transition to the second or 3rd view, nada. But the giant professional rounded corners are so cute.
