具有 .compact 风格的 UIDatePicker 不尊重内容拥抱优先级

我认为新UIDatePicker(iOS 14+) 与.compact样式无法与自动布局正确配合。

制作一个简单的布局UILabel and UIDatePicker哪里的UIDatePicker具有更高的内容优先级应该导致布局UILabel如果可用空间太多，则会被拉伸，但事实并非如此。

这就是我得到的结果：

这是示例代码：

class ViewController: UIViewController, UIGestureRecognizerDelegate {
    private let label: UILabel = {
        let label = UILabel()
        label.translatesAutoresizingMaskIntoConstraints = false
        label.text = "Label"
        label.backgroundColor = .yellow
        return label
    }()
    
    private let datePicker: UIDatePicker = {
        let datePicker = UIDatePicker()
        datePicker.translatesAutoresizingMaskIntoConstraints = false
        datePicker.preferredDatePickerStyle = .compact
        return datePicker
    }()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        view.addSubview(label)
        view.addSubview(datePicker)
        
        label.setContentHuggingPriority(.defaultLow, for: .horizontal)
        datePicker.setContentHuggingPriority(.defaultLow + 1, for: .horizontal)
        
        NSLayoutConstraint.activate([
            label.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 8),
            label.leadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor, constant: 8),
            
            label.bottomAnchor.constraint(equalTo: datePicker.bottomAnchor),
            label.trailingAnchor.constraint(equalTo: datePicker.leadingAnchor, constant: -8),
            
            datePicker.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 8),
            datePicker.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor, constant: -8)
        ])
    }
}

我错过了什么吗？这是一个已知的问题？

对我来说效果很好。将标签的水平内容拥抱优先级设置为.defaultLow-1.
