I'm trying to authorize Google APIs but after redirect to the API I always receive the error

a scheme is word before :// like http://
your URL has no scheme in URL(string: "com.googleusercontent.apps.984813079630-f828a92sqtl5lgumd4kgp9i30bs9og09")

in many oauth provider you must register a callback url yourself in google app that you define
and this is the only authorized
then see readme, callback url it's useful to get retrieve in your app the credential/token

@phimage ,
I have changed the scheme to "ios_app_bundle_id:/oauthRedirectCallback" then this problem still there

{
 "error": "invalid_client",
 "error_description": "Unauthorized"
}

I also tried use this Framework https://github.com/openid/AppAuth-iOS with same google app config and it works fine.

I make a test with callback https://oauthswift.herokuapp.com/callback/google/
http one which redirect to oauthswift://
I declare in google api console
You url is not declarable in google api console , google need http scheme
https://github.com/OAuthSwift/OAuthSwift/wiki/API-with-only-HTTP-scheme-into-callback-URL

I just add oauthswift.allowMissingStateCheck = true
and that works fine

I will try oauthswift.allowMissingStateCheck = true

actually, we cannot declare a custom callback url for ios client id
