I Want to create a view with dynamic create checkbox i know how to create c checkbox dynamic but how to manage size of view?

Here is my Code:

var spacer: CGFloat = 23

    for comments in fixer as NSArray {
        var counter = ""
        print(comments)
        counter = comments as! String

        let button = UIButton(frame:CGRect(x: 8, y: 0+spacer , width: 20, height: 20))
        button.setTitle("hi", for: .normal)
        self.assignfixerView.addSubview(button)

        let label = UILabel(frame:CGRect(x: 40, y: 0+spacer , width: 80, height: 22))
        label.text = counter
        self.assignfixerView.addSubview(label)
