Sign in with Apple fails with the system alert "Sign-Up not completed" for every app belonging to our developer team, on every device we tested. The app itself only receives ASAuthorizationError code 1001 with an empty userInfo dictionary, so there is nothing actionable on the client side.
We have systematically ruled out every configuration cause we could think of:
- Sign in with Apple capability is enabled on each App ID, set as primary (verified via the App Store Connect API)
- com.apple.developer.applesignin entitlement is present in the signed binaries and in the provisioning profiles (verified with codesign and security cms)
- Two-factor authentication is active on the test Apple ID
- No pending agreements (Paid Apps accepted; one of our apps is live on the App Store)
Reproduction matrix — ALL of these combinations fail identically:
- Devices: two different physical devices (iPhone, iPad)
- Signing: development-signed AND TestFlight (App Store distribution) builds
- Network: Wi-Fi AND cellular
- App IDs: existing ones (capability enabled more than 48 hours ago) AND a minimal reproduction app whose App ID + capability were created minutes before the test
Control test that WORKS: on the same devices, with the same Apple ID, a brand-new Sign in with Apple sign-up in App Store apps from other teams completes without any issue. The failure is therefore strictly scoped to apps of our team.
The device log (log collect) shows the following akd sequence at the moment of every attempt:
akd: [com.apple.authkit:siwa] Encountered error while fetching developer team: Error Domain=AKSQLError Code=-6003 akd: [com.apple.aaafoundation:log] Error fetching keychain items - NSOSStatusErrorDomain Code=-25300 "no matching items found" akd: [com.apple.authkit:siwa] Using personal credential state - 2, error - AKAuthenticationError Code=-7074 akd: [com.apple.AppleIDAuthSupport:general] AppleIDAuthSupport: setError: 2:M2 missing (bad password) akd: [com.apple.authkit:core] SRP authentication with server failed! (com.apple.AppleIDAuthSupport Code=2) akd: [com.apple.authkit:siwa] Error performing auth request: AKAuthenticationError Code=-7003
Given that a freshly created App ID reproduces the failure immediately while other teams' apps work on the same devices with the same Apple ID, this looks like a broken server-side Sign in with Apple provisioning/registration state for our team rather than anything we can fix ourselves.
Has anyone seen this resolved? Is there anything on the account/team level that can get a team's Sign in with Apple provisioning re-initialized? Happy to share the Team ID and full .logarchive with Apple folks via DTS/support.
