OSX Cocoa NSSearchField clear button not responding to click

I place an

and set its border to
and I found that the clear button is not clickable a.k.a. not responding when clicked. If I set the border again it's working fine.

I've been debugging this for a few hours, and found out that when I set the border to none, the text editor width will expand and shadow (cover) the clear button.

Steps to reproduce:

  1. Create an empty cocoa project/app

  2. Place an

  3. Set border to none

  4. Run the app, fill the search field and try to click the clear button

Is this a bug? Or is it intended to behave that way?

I faced with this problem and deemed it as a bug in Cocoa. But it is easy to fix in custom control or in a view controller. Just keep text field bordered in interface builder and then kill the border by having new CALayer. For example:

class ViewController: NSViewController {

@IBOutlet weak var searchField: NSSearchField!

override func viewDidLoad() {

    let maskLayer = CALayer()
    searchField.layer = maskLayer
    maskLayer.backgroundColor = searchField.backgroundColor?.CGColor

As you see, I am just restoring control color in new layer not preserving anything else. It is not perfect, but at least gives good start.
