How to Remove UIMenuController Default Items In Swift

Question

I'm trying to remove the items Look Up & Share... from the UIMenuController. How would I specifically remove the two and keep my custom one. Here is what I've achieved so far:

override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)

        // add two custom menu items to the context menu of UIWebView (assuming in contenteditable mode)


        let menuItem1 = UIMenuItem(title: "My Button", action: #selector(myButtonSel))
        UIMenuController.shared.menuItems = [menuItem1]

    }

Here is the canPerformAction I have:

  override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {

        //let shareSelector: Selector = NSSelectorFromString("_share:")

        if webView?.superview != nil {
            if action == #selector(myButtonSel){
                return true
            }
        }

        return super.canPerformAction(action, withSender: sender)
    }

Also for some odd reason, when I try to remove all the default items and keep only my custom, it does not work. Here is the code I attempted for that:

override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {

    //let shareSelector: Selector = NSSelectorFromString("_share:")

    if webView?.superview != nil {
        if action == #selector(myButtonSel){
            return true
        }
        else {

            return false
        }
    }

    return super.canPerformAction(action, withSender: sender)
}

Even when I try to remove all of the other items and keep my custom, I'm not able to do so. All I'm able to do is add my custom item.

Are you getting a SIGBART error? In that case, please check the "Connections Inspector" tab in the right hand menu? If you see some names you deleted from story board or code, but they are still there - you should delete theme from Connections Inspector. — KuboAndTwoStrings
@KuboAndTwoStrings No, I didn't get any errors, my custom menu works, but I just can't seem to remove the UIMenuController Items. The code is just ignored whenever I try to remove them. — MGames

I tried this but it worked for my by subclassing the WebView and overriding canPerformAction method, inside which I manually removed the default options.

override func canPerformAction(_ action: Selector, withSender sender: AnyObject?) -> Bool {
    if action == #selector(cut(_:)) {
      return false
    }
    if action == #selector(paste(_:)) {
      return false
    }
    if action == #selector(select(_:)) {
      return false
    }
    if action == #selector(selectAll(_:)) {
      return false
    }
    ...

    return super.canPerformAction(action, withSender: sender)
  }

I referred to this answer by Ike10 and it had worked for me. Give it a shot.
