Authorization failed: Error Domain=AKAuthenticationError Code=-7026 "(null)" UserInfo={AKClientBundleID=my bundile id}

I found this issue when integrating apple sign-in in my project. I resolved this issue by following steps.

1. Go to project 'target'
2. Then select 'Signin & Capabilites'
3. Then select '+'
4. Then select 'Sign in with Apple'. Like this image. https://imgur.com/Yw8IfwU Finally run your project & you will able to sign in with apple.

I had the same issue just now after I changed by bundle id and developer account. All the settings were correct in my developer account and on Xcode. This fixed it for me:

1. Go to the settings app
2. Tap your name at the top
3. Password & Security
4. Apps Using your Apple ID
5. Remove the app that's causing trouble

The error code (7026) seems to indicate a missing capability but this wasn't the case for me as I hadn't touched my apps capabilities. I wasn't able to track down the exact cause of this issue but what appears to work is to try again with a different simulator and sign in. Then rerun the app on the original (problematic) simulator and it will work again.

Edit to clarify the comments below: If you are getting a 7034 error code try the following. Go to appleid.apple.com find the problematic simulator and delete it from the "devices" section.

Go here and remove the not healthy simulator => works for me. Thanks the support!
