Multiple “App Store Connect Operation” Errors When Validating the App Archive

Q: I’m using SwiftPM, and the app archive validation fails with multiple “App Store Connect Operation” errors. How can I fix this issue?

A: This is a known issue (FB8761306) in Xcode 12.4 or earlier with apps that have app extensions. This issue occurs because Xcode 12 is needlessly copying third-party binary SwiftPM frameworks into your app archive’s PlugIns directory.

Apple fixed this issue in Xcode 12.5. Update to the most recent version of Xcode to apply this fix.
