iOS Swift Playgrounds Views Are Not Centered - ios

Question

So the picture says it all. I basically have a title and set the width of the label to the entire view's width and I have the text alignment to be centered. However, it's apparent that it's off to the right a little bit. I think that the playground view is cutting off a part of the view. Can anyone please tell me how to center the UILabel properly please? Thanks!
import UIKit
import PlaygroundSupport
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let title = UILabel(frame: CGRect(x: 0, y: 5, width: view.frame.width, height: 60))
title.textAlignment = .center
title.text = "Hello World!"
title.font = UIFont.systemFont(ofSize: 30, weight: .bold)
title.textColor = .white
self.view.addSubview(title)
}
}
PlaygroundPage.current.liveView = ViewController()

Setting view frames based on a view controller’s view’s frame in viewDidLoad will likely result in expected layout as auto layout has not completed its layout passes when viewDidLoad Is called. You should set your label’s frame from viewDidLayoutSubviews Instead. For example:
import UIKit
import PlaygroundSupport
class ViewController: UIViewController {
let titleLabel = UILabel(frame: .zero)
override func viewDidLoad() {
super.viewDidLoad()
titleLabel.textAlignment = .center
titleLabel.text = "Hello World!"
titleLabel.font = UIFont.systemFont(ofSize: 30, weight: .bold)
titleLabel.textColor = .white
self.view.addSubview(titleLabel)
}
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
titleLabel.frame = CGRect(x: 0, y: 5, width: view.frame.width, height: 60)
}
}
PlaygroundPage.current.liveView = ViewController()
