Use the iOS sample when you need a native Apple-platform sign-in flow with standards-based OIDC and a maintainable integration model.
This sample gives you the correct native public-client baseline for iOS. Use it for direct mobile sign-in. If the product later needs more than self-service accounts, extend the identity model deliberately instead of hiding business rules inside mobile auth code.
These pages explain the sample on Tuurio's domain. GitHub remains the code host.
