Unrecognized Selector Swift 2 Purelayout Xcode7

Question

Hello having an issue with an unrecognized selector sent to an instance exception I have searched around a bit but I've been unable to find a solution.

The error I believe is occurring in my use of PureLayout but still unsure of what is specifically causing the issue. One weird thing is that after using Carthage to make my purelayout framework I had to use a weird bridging header in order to import purelayout usually you import PureLayout.h but my code would not compile unless I imported PureLayout_Ios/Purelayout.h in my bridging header. And so I have to import PureLayout_iOS in my viewcontroller.

View:

var presenter: SignUpPresenterProtocol?
//lazy var logoImageView: UIImageView = UIImageView()
lazy var nextButton: UIButton = {
    var button = UIButton()
    button.backgroundColor = Styles.BUTTON_COLOR
    return button
}()

override func viewDidLoad() {
    super.viewDidLoad()
    self.setupSubviews()
    self.setupConstraints()
    self.setNeedsStatusBarAppearanceUpdate()
    self.presenter?.viewDidLoad()
}

private func setupSubviews()
{
    self.view.addSubview(self.nextButton)
    self.view.addSubview(self.userNameTextField)
    self.nextButton.addTarget(self, action: Selector("userDidSelectNext:"), forControlEvents: UIControlEvents.TouchUpInside)
    //self.view.addSubview(self.logoImageView)
}

private func setupConstraints()
{
    self.nextButton.translatesAutoresizingMaskIntoConstraints = false
    self.nextButton.autoMatchDimension(.Width, toDimension: .Width, ofView: self.view, withMultiplier: 0.8)
    self.nextButton.autoSetDimension(.Height, toSize: Styles.BUTTON_HEIGHT)
    self.nextButton.autoCenterInSuperview()x
}

func userDidSelectNext(sender: AnyObject)
{
    self.presenter?.userDidSelectNext()
}

And here is the error stack trace:

Answer 1

Try replacing this line...

 self.nextButton.addTarget(self, action: Selector("userDidSelectNext:"), forControlEvents: UIControlEvents.TouchUpInside)

with this instead...

 self.nextButton.addTarget(self, action: "userDidSelectNext:", forControlEvents: UIControlEvents.TouchUpInside)

You can find more info in the apple document here: Objective C Selectors

使用迦太基更新我的purelayout库后，它已修复，但不确定是什么问题，这是github上的最新changlog 。
