Was fine on macOS but now borked in the latest RC.

Still an issue with Beta 8. Perhaps beta 9 (if there's an update this week), RC or even 17.1 😬

I have the same issue if I run Xcode 15 on Ventura but it's fine on Sonoma. Were you able to fix this issue?

Also, this seems to be specific to the list selection in the sidebar in NavigationSplitView as I'm using the same app model elsewhere in my project and everything works fine. I did have the same crash in another part of my project where I use a similar UI, which was also using the app model. In that particular case, I could remove the property from the app model, which solved the issue.

Why do you need a shared static property on AppModel? This is obviously just a demo project to demonstrate the issue. In my real project, that property has to be accessible from other parts of the app Since Folder conforms to identifiable in SidebarView could you just use ForEach(folders) { folder in? Doesn't make a difference. The crash output looks like this: @ObservationIgnored private let _$observationRegistrar = Observation.ObservationRegistrar() internal nonisolated func access<Member>( keyPath: KeyPath<AppModel , Member> ) { _$observationRegistrar.access(self, keyPath: keyPath) } internal nonisolated func withMutation<Member, MutationResult>( keyPath: KeyPath<AppModel , Member>, _ mutation: () throws -> MutationResult ) rethrows -> MutationResult { try _$observationRegistrar.withMutation(of: self, keyPath: keyPath, mutation) --> Thread 1: Simultaneous accesses to 0x281bcc760, but modification requires exclusive access } @ObservationIgnored private var _selectedFolder: Folder? = nil

I have the same issue. Were you able to pass review still?

So this is the solution: Button { } label: { Label("Connect", systemImage: "bolt") .labelStyle(.titleAndIcon) } .keyboardShortcut("k", modifiers: .command) The label obviously needs a title (my mistake) but you have to specify .labelStyle(.titleAndIcon) to make the shortcut appear, which is not obvious at all.

So it seems this may be a router failure on my end and was just a coincidence that it stopped working when I updated to the latest beta. It suddenly started working again this morning. I would still recommend to check the issue in case there is something indeed causing some instability.

Right. 14, not 13. Sorry!

So adding @ObservationIgnored seems to work around the issue.

Here's a project to demonstrate the issue: import SwiftUI import Observation struct ContentView: View { var body: some View { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello, world!") } .padding() } } typealias ResolveServiceCompletionBlock = (Bool, Error?) -> Void @Observable class ServiceBrowser: NSObject { fileprivate var resolveServiceCompletionHandler: ResolveServiceCompletionBlock? = nil } It seems like the issue is with the Observation protocol as removing @Observable works.

I tried adding a new target to my project just in case the issue was with the current target I was trying to run but I get the same error even if the new target doesn't include any of the components of the other target and is just a plain "Hello, world" SwiftUI app.

With UIKit, it is possible to set the pointer style or just hide it through the UIPointerInteractionDelegate: func pointerInteraction(_ interaction: UIPointerInteraction, styleFor region: UIPointerRegion) -> UIPointerStyle? { // Hide the pointer in the screen view return UIPointerStyle.hidden() } I’m unable to find anything that would do the same on SwiftUI.

Anyone?
