GitLab Authentification

Hello, I’ve created a iOS client for iPhone via open source GitLab API.
The problem is my application was rejected by Apple. They require to provide as an authorization method the possibility of sign in with Apple.
The list of auth ways is limited and doesn’t include this option

How can I provide this function?


Seems strange to me. There are other apps on iOS that integrate with Gitlab, mostly via token auth, and certainly don’t have Apple Auth. So I don’t see how your app can be rejected because of this, when others have been accepted.
