Original GitHub issue: https://github.com/OAuthSwift/OAuthSwift/issues/630

Description:

We have implemented the flow that loggin in our iOS app opens SFSafariViewController which displays the login page handled by our own identity server. The user logs in, is redirected back to the app, and there the necessary calls our made to get the tokens we need.
This is working fine up until iOS 13.
When trying on iOS14, building with Xcode 12, the logging in and redirecting back is working as expected. But
when the OAuthSwift framework tries to get the access token in the function
fileprivate func requestOAuthAccessToken(..)

it fails, because it encounters an error, 403 Forbidden.
Any ideas what kind of differences between Xcode 12/iOS 14 and Xcode 11/iOS 13 could be causing this?

Thank you.

Using this I am able to get access token in Xcode 13, ios 14. Please try this.
self.oauthswift?.client.credential.oauthToken

Thank you for your answers. However I'm not able to reproduce the issue anymore reliably.
