Xcode – Why my Navigation and Normal Buttons text and images are not visible but actionable?

Why my Navigation and Normal Buttons text and images are not visible but actionable, when i build app on iphone and as well as when i check app after building an app on simulator?

This is how i am adding button to navigation bar:

    @objc func moreNavigationButton() -> UIBarButtonItem {

    let barButton:UIButton = UIButton.init(type: .custom)
    barButton.addTarget(self, action:#selector(moreNavigationButtonClicked), for: .touchUpInside)
    barButton.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
    barButton.setImage(UIImage(named: "ic_more"), for: .normal)
    barButton.imageView?.contentMode = .scaleAspectFit
    
    let barButtonItem:UIBarButtonItem = UIBarButtonItem.init(customView: barButton)
    barButtonItem.width = 30
    
    return barButtonItem
}

In viewWillAppear() function i am calling the above method like following:

    self.navigationItem.rightBarButtonItems = [self.moreNavigationButton()]

    The below extension was causing this problem. Now i commented it and it is solved.

    extension UIButton {
    open override func layoutSubviews() {
            super.layoutSubviews()
            if imageView != nil {
                imageEdgeInsets = UIEdgeInsets(top: 5, left: (bounds.width - 5), bottom: 5, right: 5)
                titleEdgeInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: (imageView?.frame.width)!)
            }
        }
}

    All right now we have different setting up for button in my side I usually do like that

    navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(addTapped)) 
navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Add", style: .plain, target: self, action: #selector(addTapped))

    then after I set 2 barButtonItem

    let add = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(addTapped))
let play = UIBarButtonItem(title: "Play", style: .plain, target: self, action: #selector(playTapped))

    Here I had them to navigation items
    navigationItem.rightBarButtonItems = [add, play]

    I suppose you need to set Bar button item instead of button.
