This is a hack, but I created an objc header to make the UITraitCollection definition available to watchOS. This allowed for the UIColor(named name: String, in bundle: Bundle?, compatibleWith traitCollection: UITraitCollection?) method to be accessed. Objc header file added to the framework: #if TARGET_OS_WATCH @import UIKit; @interface UITraitCollection : NSObject @end #endif

It seems to be fixed in Xcode 12.5 https://forums.swift.org/t/incomplete-crash-log-symbolication-for-bitcode-enabled-apps-linked-with-packages-containing-resources/42696/5

I am also seeing this issue. We also see it in a more simple case: ScrollView { HStack { ... } .simultaneousGesture( DragGesture(minimumDistance: 0) // ... ) } Was using simultaneousGesture to get around this issue: https://developer.apple.com/forums/thread/763436 But now it is broken as well.

I am also seeing this issue where successfully uploaded builds do not show in TestFlight / App Store Connect. We are using Xcode 26 Beta 7 and altool with an app specific password.
