Even though everything is perfect and set up correctly, the accessToken is not returning.

• I'm running my project in xCode on WmWare

• I'm testing it on a real device, I'm connected to the PC via cable.

• I am switching my application to Spotify, and after approval for the authorize process, it returns to the application, but the accessToken returns nil every time.

• I am sure that my code verifier code challenge client id, client secret and redirect uri data are correct.

return Warning :

 Failed to initiate session: invalid_grant
Error domain: com.spotify.sdk.login
 Error code: 1
User Info: {
    NSLocalizedDescription = "invalid_grant";
}
