Experiencing the same issue. I'm on Xcode 15 beta 6.
The same issue happened to me on beta 5. Upgrading to beta 6 worked a few days ago.
However, I recently updated to the latest iOS 17 beta and now it's crashing again with the 'Symbol not found' error.
Hope this gets fixed soon.

I'm on Xcode 15 beta 6 and simply removing the default values caused the model container to crash.
Making the properties optional worked for me.
Replacing #Preview with the good old struct ContentView_Previews: PreviewProvider works for me.
If y'all can't wait for the fix, this workaround should work.
Thanks to the previous comment!
