App Store submission validation failed: Missing info.plist value WKApplication

I've developed a Multiplatform app under Xcode 26 (currently using 26.2 17C52). The current destinations of the single target are Mac, iPad and Mac(designed for iPad). The minimum deployments are MacOS 15.6 and iOS 18.6. All destinations build and perform correctly on physical devices (running OS 26 versions).

The MacOS version has been submitted successfully to the AppStore for TestFlight usage. However, the iPad version shows a submission validation failure:

Missing Info.plist value. A value for the key “WKApplication”, or “WKWatchKitApp” if your project has a WatchKit App Extension target, is required in “xxxxx.app/xxxxx.app” bundle. For details, see: https://developer.apple.com/documentation/watchkit/creating_independent_watchos_apps/setting_up_a_watchos_project (ID: 4911506c-39c3-4b69-a8bb-5e5dcd3dc2fb)

The app has no WatchKit version (although one's planned for a future release). The Target's Build Settings include a "watchOS Deployment Target" and Info.plist values related to WatchKit. The Build Settings also include similar settings for TVOS and VisionOS.

I'm unable to delete the aforementioned Build Settings (Can't select & use the delete key). The link in the message provides no help.

Is this a bug in Xcode, or am I missing something?

Regards, Michaela

Are you able to share a copy of the Xcode project file somewhere where I could look at it?

Thanks Ed, but I've just solved the problem. I'd inadvertently saved an archive from this App's build into the App's source directory. On deleting that extraneous archive, Validation then complained about Background Processing plist key (the app uses CoreData - CloudKit sync). Adding a plist entry fixed that error and now the app has passed validation and been uploaded - but doesn't yet appear in my iOS apps (for TestFlight testing).
