Alamofire request always fails because of cancelled

[donpironet]

I'm having a RegisterManager like this:

    class RegisterManager {
      private let manager : Alamofire.Manager

      init(){
        let configuration = Timberjack.defaultSessionConfiguration()
        manager = Alamofire.Manager(configuration: configuration)
      }
    }

Then I have some methods on RegisterManager for example:

     func loginUser(username: String, password: String, completionHandler: CompletionHandler) {

            let parameters: [String:String] = [
                    "username": username,
                    "password": password,
                    "scope": "user_basic",
                    "grant_type": "password"
            ]

            let headers = [
                    "Authorization": "Basic \(getBase64Credentials())",
                    "Content-Type": "application/x-www-form-urlencoded"
            ]

            manager.request(.POST, String(format: "%@%@", arguments: [kAPIHost, "/oauth/token"]), parameters: parameters, headers: headers).responseJSON {
                response in

                if let _ = response.result.value {
                    completionHandler(success: true)
                } else {
                    completionHandler(success: false)
                }
            }
        }

When I do the call it always fails because it's cancelled. When I just change manager.request to Alamofire.request it works. I found here on the github that you need to have a let in your class so I did but still the same problem.

What I'm doing wrong?

@donpironet I believe you need _.sharedInstance_ on the end of your _manager_ constant.

[donpironet]

But then I have a instance again with the default configuration?

@donpironet You'll need to keep a reference to your manager around. You requests are being cancelled because the manager you're using is being deallocated. I like to use a static let sharedManager in my Manager subclass to maintain a single instance.

[donpironet]

But I have a private let variable in my RegisterManager? So why is that not working?

[jshier]

Because it's not static. A private let is just an instance variable, one that's deallocated with the instance. Create a static let sharedManager = RegisterManager() and use it for your request calls (i.e. RegisterManager.sharedManager.request()).

I found the problem. It was indeed in the class that creates my RegisterManager. I didn't save a reference to it. Feeling so stupid.
