UIButton not added to subview swift - swift

Question

I created a UIButton and added it to my view controller but on load, the button does not show despite adding it to subview and constraints
var plusBtn: DefaultBtn = {
let plusBtn = DefaultBtn(type: .custom)
plusBtn.translatesAutoresizingMaskIntoConstraints = false
return plusBtn
}()
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .white
view.addSubview(plusBtn)
plusBtn.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 20).isActive = true
plusBtn.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -20).isActive = true
plusBtn.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 20).isActive = true
plusBtn.setTitle("BUT WHY", for: .normal)
}
class DefaultBtn: UIButton {
override func awakeFromNib() {
// layer.cornerRadius = self.frame.size.height / 2
layer.borderWidth = 1
layer.borderColor = UIColor.black.cgColor
backgroundColor = .white
// heightAnchor.constraint(equalToConstant: 50).isActive = true
// widthAnchor.constraint(equalToConstant: 50).isActive = true
translatesAutoresizingMaskIntoConstraints = false
setTitleColor(.black, for: .normal)
}
}
any help is appreciated

Try
view.backgroundColor = .red
OR
plusBtn.setTitleColor(.red, for: .normal)
the default title color of the button is white which is same as the view's background color
class DefaultBtn: UIButton {
override init(frame: CGRect) {
super.init(frame: frame)
shared()
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func shared () {
layer.borderWidth = 1
layer.borderColor = UIColor.black.cgColor
backgroundColor = .white
translatesAutoresizingMaskIntoConstraints = false
setTitleColor(.black, for: .normal)
}
}
