App run fine on simulators but not on MacBookPro 14 Inch and iPad ? I Don't understand beta version run only on simulators ?
Swift Data doest not work on physical devices such as MacPro or Ipad when I installed Beta 2. Even template project does not work and throw this error. How can I revert Beta 1 ?
I had the same mistake.
You should update the Xcode version to «Version 15.0 beta 2 (15A5161b)».
After that everything works fine on physical devices with iOS 17.0 (21A5277h) and this error no longer occurs.
I am running Xcode 15 beta 3 and iOS 17 beta 3 and this bug still exists
Remedy is to comment out the new style preview and add the old style preview.
//#Preview {
// ContentView()
//}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
That worked! Thanks RawMean :)
also for me thanks!
Thanks for the fix!
Any idea what's going on? The #Preview macro is supposed to be one of our new conveniences. Not fully baked yet? Or perhaps just a situation that crops up only on occasion?
