Error on signing up

[ghost]

using this example on the swift 2 branch, the app builds, Ive set up the cloud code side, parse shows its signing up the users through the login screen when the app builds and runs on my phone but i get a constant activity spinner and the following error:

                let identityToken = object as! String
                self.layerClient.authenticateWithIdentityToken(identityToken) { authenticatedUserID, error in
                    if (!authenticatedUserID.isEmpty) {
                        if (completion != nil) {
                            completion(success: true, error: nil)
                        }
                        print("Layer Authenticated as User: \(authenticatedUserID)")
                    } else {
                        completion(success: false, error: error)
                    }
                }
            } else {
                print("Parse Cloud function failed to be called to generate token with error: \(error)")
            }
        }
    }
}

getting a Thread 1: Exc Breakpoint on this line of code " if(authenticatedUserID.isEmpty){

@lhumphreys73 Thanks for reporting the issue. The app (swift 2 branch) seems like is running fine on both simulator and my iPhone (iOS 9 beta 3).
In order to isolate the issue, can you provide me these info?
Do you encounter the same problem:

1. on Xcode 7 simulator? (By the way, what is your Xcode 7 version?)
2. with Xcode 6 on both simulator and iPhone?
3. with https://github.com/layerhq/Layer-Parse-iOS-Example project?
   If none of the above works, probably it is your Parse Cloud Code or configuration issue?
   If any of the above works, then... mmm.. let me think. 😛

Thank you, resolved, it was a configuration issue.
