12,653 PointsWhat am I doing wrong in this challenge?
I'm trying to match what it is looking for but it's not giving me much information as to what is wrong. It says I'm not doing all the constraints but I am.
class MyViewController: UIViewController {
let sampleView = UIView()
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(sampleView)
}
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
sampleView.translatesAutoresizingMaskIntoConstraints = false
// Add constraints below
let CenterX = NSLayoutConstraint(item: sampleView, attribute: .centerX, relatedBy: .equal,
toItem: view, attribute: .notAnAttribute, multiplier: 1.0, constant: 0.0)
let CenterY = NSLayoutConstraint(item: sampleView, attribute: .centerY, relatedBy: .equal,
toItem: view, attribute: .notAnAttribute, multiplier: 1.0, constant: 0.0)
let Height = NSLayoutConstraint(item: sampleView, attribute: .height, relatedBy: .equal,
toItem: view, attribute: .notAnAttribute, multiplier: 1.0, constant: 50.0)
let Width = NSLayoutConstraint(item: sampleView, attribute: .width, relatedBy: .equal,
toItem: view, attribute: .notAnAttribute, multiplier: 1.0, constant: 50.0)
view.addConstraints([CenterX, CenterY, Height, Width])
}
}
