Breaking issue: No visible @interface for 'OIDAuthorizationResponse' declares the selector 'tokenExchangeRequestWithAdditionalParameters:'

[RebinX1]

Yesterday my Xcode app and Simulator got updated automatically to the latest version, Xcode 15.3 and IOS 17.4.

After that i tried to run one of my project and it started to fail, i thought it was xcode being xcode and it should be an issue with my project and configuration.

After many research i decided to updated all of my packages. my project include Firebase and GoogleSignIn and some other packages. starting to update one by one i was still getting the same error, then when i reached the GoogleSignIn it was still the same version 7.0.0, i decided to remove it and its implementation from my project.

then all of a sudden the error disappeared! i add it again to my project and then i got a different error inside that library!

the error was:

No visible @interface for 'OIDAuthorizationResponse' declares the selector 'tokenExchangeRequestWithAdditionalParameters:'

i dont know what to do right now, my app depend highly on google sign in and this is breaking that authentication state.

i tried to decrease firebase version and deployment version but none worked so far!

What version of AppAuth are you seeing pulled in? If it's 1.7.0, then you can use this method and pass nil to the additionalHeaders parameter.

the AppAuth that i see is indeed 1.7.0, as its shown in the provided image.

i just added GoogleSignIn library and that issue appears.

Gotcha. Please take a look at my previous comment and update your method call. This will unblock you for now while I work on a patch release to add back the method that was removed.

thanks, i checked the previous comment and its code, not sure what you meant by updating my method call.

but this is the code that i use to call the googleSignIn:

`import Foundation
import GoogleSignIn
import GoogleSignInSwift

final class GoogleSignInHelper {

@MainActor
func signIn() async throws -> GoogleSignInResultModel{
    guard let topVC = Utilities.shared.topViewController() else { throw URLError(.cannotFindHost) }
    
    let gidSignInResult = try await GIDSignIn.sharedInstance.signIn(withPresenting: topVC)
    
    guard let idToken = gidSignInResult.user.idToken?.tokenString else { throw URLError(.badServerResponse) }
    
    let accessToken = gidSignInResult.user.accessToken.tokenString
    let name = gidSignInResult.user.profile?.name
    let email = gidSignInResult.user.profile?.email
    
    let tokens = GoogleSignInResultModel(idToken: idToken, accessToken: accessToken, name: name, email: email)
    
    return tokens
}

}`

and i wanted to mention that the build fails to run, i am not sure how to update the library code. further assistance is appreciated.

I apologize. Yes, this problem needs to be fixed here and not with you. AppAuth 1.7.0 is breaking Google Sign-In iOS. I am working on a fix right now.

[RebinX1]

okay so should i just update my packages to the latest version and it should work fine, right?

[mdmathias]

You will have to wait on a fix for AppAuth. I am working on it right now. Google Sign-In iOS (GSI) depends upon AppAuth, and a version of AppAuth released that broke GSI. Please stay tuned. Sorry for this disruption.
