Please Update Your code with mine one and replace secret with your key.i'm using OAuthSwift library in my project. Also Don't forgot to add URL Type Schemes in your project. and Make Role as Editor
let kClientID = ""
func doOAuthGoogle(){
let oauthswift = OAuth2Swift(

You must have to USE Handler Method
//MARK:- Get URL -
func getURLHandler() -> OAuthSwiftURLHandlerType {
guard let type = self.formData.data?.handlerType else {
return OAuthSwiftOpenURLExternally.sharedInstance
}
switch type {
case .external :
return OAuthSwiftOpenURLExternally.sharedInstance
case .`internal`:
if internalWebViewController.parent == nil {
self.addChildViewController(internalWebViewController)
}
return internalWebViewController
case .safari:
#if os(iOS)
if #available(iOS 9.0, *) {
let handler = SafariURLHandler(viewController: self, oauthSwift: self.oauthswift!)
handler.presentCompletion = {
print("Safari presented")
}
handler.dismissCompletion = {
print("Safari dismissed")
}
return handler
}
#endif
return OAuthSwiftOpenURLExternally.sharedInstance
}
}
