GPPSignIn does not call openURL: sourceApplication method in appDelegate after return

Question

I use Google plus Framework in my application, but I can’t get a response when I return from the Google-Plu application. I added the URL-Scheme , I have the same kit in the console and in the application. I also have the correct CLIENTID . Does anyone have the same problem?

Perhaps the problem occurs in iOS 8 or Xcode 6 ??

Now I get this error:

 Error Domain=com.google.GooglePlusPlatform Code=-1 "keychain error" UserInfo=0x175263ec0 {NSLocalizedDescription=keychain error} 

thanks
