iOS11 UIBarButtonItem action not get called

Question

I used Xcode9 Beta6 to build the project, the action was called correctly on iOS10 device, however it is not work on iOS11 device.

In My project, there are some view

Answer 1

In my case I was setting up the button and instantiating it as a property of the vc

class myVC: UIViewController {
let closeBarButtonItem = UIBarButtonItem(image: image, style: .plain, target: self, action: #selector(close(_:)))
}

If I moved this to ViewDidLoad it resolved the problem

class myVC: UIViewController {
override func viewDidLoad() {
    super.viewDidLoad()
    let closeBarButtonItem = UIBarButtonItem(image: image, style: .plain, target: self, action: #selector(close(_:)))
}

}
