使用自动调整集合视图单元格大小时的自动布局警告

Question

我正在使用自调整大小的集合视图单元格，运行时似乎可以正确显示它，但是编译器收到一堆警告，说的都是相同的（运行Xcode 12.1）

collectionViewCell的

contentView的translationsAutoresizingMaskIntoConstraints为false，并且缺少对单元的约束，这将导致单元自动调整的性能不合标准。请保持contentView的translationsAutoresizingMaskIntoConstraints为真，否则请在contentView和单元格之间提供约束。

这是我的手机的代码

    override init(frame: CGRect) {
    super.init(frame: frame)
    contentView.addSubview(content)
    contentView.addSubview(imageView)
    content.translatesAutoresizingMaskIntoConstraints = false
    imageView.translatesAutoresizingMaskIntoConstraints = false
    contentView.translatesAutoresizingMaskIntoConstraints = false
     // this is to enable dynamic height for cells 
    contentView.widthAnchor.constraint(equalToConstant: UIScreen.main.bounds.width - 40).isActive = true
       // content is a UILabel I'm using to display text
    content.topAnchor.constraint(equalTo: contentView.topAnchor).isActive = true
    content.leftAnchor.constraint(equalTo: contentView.leftAnchor).isActive = true
    content.rightAnchor.constraint(equalTo: contentView.rightAnchor).isActive = true
    content.bottomAnchor.constraint(equalTo: contentView.bottomAnchor).isActive = true
     // imageView is an image for content
    imageView.translatesAutoresizingMaskIntoConstraints = false
    imageView.topAnchor.constraint(equalTo: contentView.topAnchor).isActive = true
    imageView.bottomAnchor.constraint(equalTo: contentView.bottomAnchor).isActive = true
    imageView.leftAnchor.constraint(equalTo: contentView.leftAnchor).isActive = true
    imageView.rightAnchor.constraint(equalTo: contentView.rightAnchor).isActive = true
    layer.borderWidth = 1
    layer.borderColor = UIColor.green.cgColor
}

我的代码有什么问题吗？我应该担心这些警告吗？
