I have the exactly the same issue.

The problem is, that I would like to work with ActivityKit, which is enabled in 14.1 :((

// When it is dismissed, there is no way to bring it back. DocumentGroup(newDocument: { TestDocument() }) { file in ContentView() } // I can bring it back by opening it with its ID. WindowGroup(id: "TestWindow") { TestWindowView() } .windowStyle(.plain) Here is some more information about the issue.

Same here! We basically cannot launch with iOS 18, because of this bug... The problem is that we have a lot of dependencies that use this, so we cannot make a viable workaround.

If a lot of our package dependencies use the NSDecimal, that means that we cannot ship until for iOS 18 on day one?

This is fixed in the latest Xcode!

DocumentGroup is so broken. Every new Xcode seem to produce just more and more issues with it.

Thank you, filed one here: FB15689459

There is also an issue on iOS 18.3: whenever I change the name of the file, the toolbar items disappear.

Is there a solution for ios 18.4? We have 30k+ users affected and it makes like half of our app unusable.

I had to uncheck the support for "iCloud Documents", and it started working!
