PLATFORM AND VERSION iOS Development environment: Xcode 26.2, macOS x Run-time configuration: iOS The issue does not seem to be limited to a specific version.
DESCRIPTION OF PROBLEM We are reaching out to request in-depth technical assistance regarding an intermittent issue with Sign in with Apple implementation in our application.
[Technical Status] We have confirmed that our technical implementation is correct. All necessary code and Xcode Capabilities are properly configured, and the service is working perfectly for the vast majority of our users. However, a small subset of users is consistently encountering "Unknown" Error (Error Code 1000), which prevents them from logging in entirely.
[Identified Scenario] Currently, the only reproducible case we have found involves Child Accounts (protected accounts) under Family Sharing, specifically when the user's age is set below the regional requirement for a standalone Apple ID. However, we are receiving reports from other users who do not seem to fall into this category.
[Requests for Clarification] To resolve this issue and support our users, we would like to obtain clear answers to the following questions:
Root Cause: Why does Error 1000 occur specifically for a small number of users while the service works for most others?
Other Scenarios: Are there any known cases or conditions other than the "Child Account" age restriction that trigger this specific error?
Account-side Issues: If our code and configurations are verified to be correct, should we conclude that this is an issue specific to the individual's Apple ID/Account status?
If so, could you provide a troubleshooting guide or official recommendation that we can share with these users to help them resolve their account-related issues?
We are committed to providing a seamless authentication experience and would appreciate your expert insight into these edge cases.
Thank you for your support.
