I have the same problem rebooting my iPhone and Mac Pro, runs fine in the simulator, when I launch the app on the phone, the screen just stays black, if I quick the run in Xcode the app will now launch on the phone. Any one else have this problem or a solution Specs: Mac Pro 2013 6 Core 128Gb Ram BigSur Beta 2 Iphone X Max256gb iOS 14 Beta Xcode 12 Beta 2

Yes tried that and also remove the device from my Device list in Certificate, Identifiers, and Profile, no luck either as soon as you plug in the phones they show up for a mia few seconds and then unmount with no error or warning. I also have multiple team memberships and multiple different apple silicon mac mini and MacBook pro, all exhibiting the same problem.

Issue has been fixed in XCode Beta 3 and macOS 13 Beta 3

So seem to build with Xcode 14 beta 4 allows our app to get around the crash problem building for 15.4, but we still have a problem with displaying PDF files in a PDFView that is crashing the app now, we noticed Affinity designer can no longer export to PDF as that will crash the app, to probably the problem is deep in Apples private frameworks

Yes the project has swift packages and simple frameworks for asset storage

I have the same problem with a MacCatalyst app that has been running for two years I can no longer run the app, does any one have a update?
