我试图加载uiView。这个视图应该有50点距离右下方标签。但模拟器显示更多的小距离。所以我试图设置uiView的背景色来检查这个视图如何占用，但它不工作？我的代码的主要问题是什么？
这里是屏幕截图和代码

private let helpLabelView: UIView = {
        let container = UIView()
        let label1 = UILabel(frame: CGRect(x: 0, y: 0, width: 300, height: 20))
        label1.text = "비밀번호를 설정해주세요."
        label1.font = UIFont(name: "Pretendard-Regular", size: 15)
        label1.backgroundColor = .cyan
        
        let label2 = UILabel(frame: CGRect(x: 0, y: 20, width: 300, height: 20))
        label2.text = "(영어 대소문자, 숫자, 특수문자 각 1개 이상 사용)"
        label2.font = UIFont(name: "Pretendard-Regular", size: 15)
        label2.backgroundColor = .green
        
        container.addSubview(label1)
        container.addSubview(label2)
        
        container.backgroundColor = .brown // this line not applied
        
        return container
    }()

view.addSubview(helpLabelView)
helpLabelView.translatesAutoresizingMaskIntoConstraints = false

pwLabel.bottomAnchor.constraint(equalTo: pwField.topAnchor, constant: -11),
            pwLabel.leftAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leftAnchor, constant: 20),
            helpLabelView.bottomAnchor.constraint(equalTo: pwLabel.topAnchor, constant: -50),
            helpLabelView.leftAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leftAnchor, constant: 20),

• pwLabel位于HelpLabelView标签下方附近**所有视图均设置为活动 *
