How can I make my McPickerView Multiline in swift?

[AndrewFakher]

I have an McPickerView how can I make it multiline? I have some long text.

Here is my code :
```
let customLabel = UILabel()
customLabel.textAlignment = .center
customLabel.lineBreakMode = .byWordWrapping
customLabel.numberOfLines = 0
customLabel.sizeToFit()
mcPickerView.label = customLabel

**but nothing changed it still one single line.**
