Google OAuth 2.0 invalid_client Unauthorized - ios

Question

I used this code to authorize Google+ via OAuth 2.0
oauthswift = OAuth2Swift(
consumerKey: "984813079630-f828a92sqtl5lgumd4kgp9i30bs9og09.apps.googleusercontent.com",
consumerSecret: "AIzaSyD13MBv78yWIjl4TX9jOOT9AWuEkYdVSPQ",
authorizeUrl: "https://accounts.google.com/o/oauth2/v2/auth",
accessTokenUrl: "https://www.googleapis.com/oauth2/v4/token",
responseType: "code"
)
let handle = oauthswift.authorize(
withCallbackURL: URL(string: "com.googleusercontent.apps.984813079630-f828a92sqtl5lgumd4kgp9i30bs9og09:/oauth")!,
scope: "profile", state:"GOOGLE",
success: { credential, response, parameters in
print(credential.oauthToken)
// Do your request
},
failure: { error in
print(error.localizedDescription)
print((error as OAuthSwiftError).errorUserInfo)
}
)
but the result always failed
The operation couldn’t be completed. (OAuthSwiftError error -11.)

Could you please correct it ?

Answer 1

You must remove replace withCallbackURL "com.googleusercontent.apps.984813079630-f828a92sqtl5lgumd4kgp9i30bs9og09:/oauth" with "your.bundle.id:/oauth2Callback"
Commentary from demo OAuthSwift:
For googgle the redirect_uri should match your this syntax:
your.bundle.id:/oauth2Callback
In plist define a url schem with: your.bundle.id
After these changes, I still had this problem. Found solution:
I removed the customerSecret by an empty string then.. it worked.
I hope to help you with my answer above!
