Usage

Setup

Provide GoogleSignIn with your apps Google API Client ID and any Google API scope

GoogleSignIn.shared.clientId = "<Google API Client ID>"
GoogleSignIn.shared.addScope("<Google API Scope>")

GoogleSignIn.shared.delegate = self
GoogleSignIn.shared.presentingWindow = view.window
GoogleSignIn.shared.signIn()

func googleSignIn(didSignIn auth: GoogleSignIn.Auth?, user: GoogleSignIn.User?, error: Error?) {
    if let error = error {
        print("Error signing in: \(error)")
        return
    }
    // Route user to app
}

Use Access Token

Although you can access the token via GoogleSignIn.shared.auth?.accessToken it is recommended you use GoogleSignIn.shared.refreshingAccessToken. If the token is expired, this method will refresh and return a new valid token.

GoogleSignIn.shared.refreshingAccessToken { token, _ in
    guard token != nil else {
        return
    }
    // Use token
}

Sign out

GoogleSignIn.shared.signOut()

Fetch profile

GoogleSignIn.shared.getProfile { user, error in
    //
}

note: this is done for you once by default when user logs in.

Get user email with sign in

To get a users email, make sure that you set this before sign in.

GoogleSignIn.shared.email = true

You can also disable profile (default true)

GoogleSignIn.shared.isSignedIn
