Set a special string to the UILabel, but the part of string is duplicated and be strange

My user report a bug that the texts is strange and he did not taped that. So I get the texts and create a simple project, only create a label and set the texts to it. The texts is here:

【Does this sound natural?】\n \"Who's that?\" \"That's Tom when he was a kid.\" \"Do you have a same picture of Mary?

If I do not limit the number of label's line, there is no issue, but when set the number of line to 3, the text "That's Tom when occurred two times! And texts is became strange.

enter image description here

All code is here

class ViewController: UIViewController {
    lazy var label: UILabel = {
       let label = UILabel(frame: CGRect(x: 50, y: 100, width: 220, height: 100))
        label.numberOfLines = 3
        label.font = UIFont.systemFont(ofSize: 14)
        self.view.addSubview(label)
        return label
    }()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        
        self.view.backgroundColor = .lightGray
        self.label.text = "【Does this sound natural?】\n \"Who's that?\" \"That's Tom when he was a kid.\" \"Do you have a same picture of Mary?"
    }
}

According to the discussion here it is a bug occurring after iOS 15.4.

There is a workaround mentioned in the above thread.

I also faced the same issue and I changed the UILabel to a UITextView with the two options

label.textContainer.maximumNumberOfLines = 3
label.textContainer.lineBreakMode = .byTruncatingTail

Check if either of workarounds will work in your case.
