Why do I have to do this, shouldn't autolayout figure out the height on it's own?

sample.swift

class GKTextAlertContentView: UIView {

    @IBOutlet var titleLabel: UILabel!
    @IBOutlet var textLabel: UILabel!
    @IBOutlet var textField: UITextField!
    @IBOutlet var submitButton: UIButton!

    override func intrinsicContentSize() -> CGSize {
        
        let titleSize = titleLabel.intrinsicContentSize()
        let textSize = textLabel.intrinsicContentSize()
        let textFieldSize = textField.intrinsicContentSize()
        let btnSize = submitButton.intrinsicContentSize()
        
        let dist: CGFloat = 10.0
        let height = dist + titleSize.height + dist + textSize.height + dist + textFieldSize.height + dist + btnSize.height + dist + dist
        return CGSize(width: 280, height: height)
    }
}
