Native WeatherKit fails for our app on both development and TestFlight distribution builds, with the WeatherKit service enabled. Team ID: YCF2TGZAX8 Bundle ID: org.walktalkmeditate.pilgrim Call: try await WeatherKit.WeatherService.shared.weather(for: location, including: .current) Error (immediate, every call): Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" What we've verified: WeatherKit enabled under BOTH the Capabilities tab AND the App Services tab for this App ID. com.apple.developer.weatherkit entitlement confirmed in the signed binary (codesign -d --entitlements). Fails identically on (a) Xcode-direct development builds and (b) TestFlight distribution builds. Physical device (iPhone SE 3rd gen) signed into iCloud / an Apple Account. Survives app delete + reinstall AND a device reboot, on both build types. GPS/CoreLocation works fine; only WeatherKit auth fails. Not a timeout or rate-limit. First appeared on Xcode 26 beta; never resolved on stable Xcode 26.3 (17C529), iOS 18.x. This matches the pattern in threads 786126, 810137, 811225, and 789900, where the WeatherKit auth backend hasn't registered/synced the bundle ID for JWT issuance even with App Services on, and Apple resolves it server-side. Could someone check the backend WeatherKit registration for org.walktalkmeditate.pilgrim? Happy to provide a sysdiagnose. Will also file a Feedback report and add the FB number here.
