[iOS] How to get authorisation code to generate access_token and refresh_token at backend web api?.

[31gfcheqbjqv5sylsrna]

Hi,

We are having some trouble implementing the IOS Spotify SDK. We use it in the context of user authorisation in order to get the `code`. We pass the `code` to our api (where it is transformed). Our api (nodejs) calls a spotify token endpoint and we keep getting an error `code_verifier was incorrect`. We tried regenerating it and we still get the same error. The `redirectUri` is correctly registered and we use it with both api and mobile. On Android it works correctly (with and without `code_verifier`).

If anyone can help, please let us know. Thanks
