I have a personal iOS project that I also compile for macOS with Catalyst. When built with Xcode 26.x, everything is linked correctly. When built with Xcode 27 betas, the following runtime error occurs:

Termination Reason:  Namespace DYLD, Code 4, Symbol missing
Symbol not found: _UIFontTextStyleCallout
Referenced from: <046ED276-F81A-31B4-82FF-6DC82E9041BC> /Applications/Photo Library.app/Contents/MacOS/Photo Library
Expected in:     <298B64F6-9BC0-3BFB-BE72-EBDC2BE0FF19> /System/Library/Frameworks/AppKit.framework/Versions/C/AppKit

Any assistance?

Thanks
