Swift make label overlap status bar - swift

Question

I have this label in Swift
let top_error_rep: UILabel = {
let lb = UILabel()
lb.text="Password should be at least 6 charachters"
lb.textColor = UIColor(r: 230, g: 230, b: 230)
lb.backgroundColor = .red
return lb;
}()
I show it only when user input is less than 6 characters. Now when I show it status bar overlaps the input, how can I prevent that?
This is how it looks like

Answer 1

Set label's position.
After you add the label to subViews of your view. You need to set it's position by using constraint like this:
top_error_rep.topAnchor.constraint(equalTo: self.topAnchor).isActive = true
top_error_rep.leftAnchor.constraint(equalTo: self.leftAnchor).isActive = true
top_error_rep.rightAnchor.constraint(equalTo: self.rightAnchor).isActive = true
top_error_rep.heightAnchor.constraint(equalToConstant: 20).isActive = true
or you can use different way. Google for Auto layout programmatically swift
Make it only show when user input is less than 6 characters

EDIT
add this to your ViewController to hide the status bar
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
//Add below line.....
UIApplication.shared.isStatusBarHidden = true
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
//It will show the status bar again after dismiss
UIApplication.shared.isStatusBarHidden = false
}
override var prefersStatusBarHidden: Bool {
return true
}
