Swift Alamofire + Promise catching - swift2

Question

Folks, The following works except for the catch, xcode errors out with expected member name following '.'
Is this the proper way to promisify with PromiseKit?
All suggestions welcome! Thanks!
#IBAction func loginButtonTapped(sender: AnyObject) {
let email = userEmail.text!
let password = userPassword.text!
func onSuccess(success:Bool, message:String, token: String) -> Promise<Void> {
if success {
NSUserDefaults.standardUserDefaults().setBool(true, forKey: "isUserLoggedIn")
NSUserDefaults.standardUserDefaults().synchronize()
self.dismissViewControllerAnimated(true, completion: nil)
} else {
let myAlert = UIAlertController(title: "Alert", message: message, preferredStyle: UIAlertControllerStyle.Alert)
let okAction = UIAlertAction(title: "Try Again", style: UIAlertActionStyle.Default, handler: nil)
myAlert.addAction(okAction)
self.presentViewController(myAlert, animated: true, completion: nil)
}
return Promise { resolve, reject in
return resolve()
}
}
func onFailure(error:NSError) -> Promise<Void> {
return Promise { resolve, reject in
return reject(error)
}
}
Login(email, password: password).then(onSuccess).catch(onFailure)
}
private func Login(email: String, password: String) -> Promise<(success:Bool, message:String, token: String)> {
let parameters: [String: String] = [
"username" : email,
"password" : password
];
let endpoint = "https://api.foo.bar/login"
return Promise { resolve, reject in
Alamofire.request(.POST, endpoint, parameters: parameters, encoding: .JSON)
.validate()
.responseJSON { (response) in
guard response.result.error == nil else {
logger.debug(response)
let result:(success:Bool, message:String, token: String) = (false, "Login Failed", "")
return resolve(result)
}
if let value = response.result.value {
let apiResponseJSONBody = JSON(value)
let result:(success:Bool, message:String, token: String) = (true, "", token: apiResponseJSONBody["token"].string!)
return resolve(result)
}
}
}
}
