Is UITextField+UIPickerView supported under Mac Catalyst?

Question

In my iOS app I have a textfield with a picker view assigned to it's inputView. On iOS devices the picker view pops up whenever the user taps the textfield. The same code does not do that, however, when I run it as a Mac/Catalyst app. My debug effort so far shows that the picker view methods are not called at all, so if the Mac requires additional textfield delegate methods to take focus away from the Mac's keyboard? Any idea how to make this work on a Mac? A barebones example code is below.

class ViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource, UITextFieldDelegate {
@IBOutlet weak var myTextField: UITextField!

var myPickerView : UIPickerView!
var pickerData = ["Alpha" , "Bravo" , "Charlie" , "Delta"]

override func viewDidLoad() {
    super.viewDidLoad()

    self.myPickerView = UIPickerView(frame:CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: 300))
    self.myPickerView.delegate = self
    self.myPickerView.dataSource = self

    self.myTextField.delegate = self
    self.myTextField.inputView = self.myPickerView

}

func numberOfComponents(in pickerView: UIPickerView) -> Int {
    return 1
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
    return pickerData.count
 }
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
    return pickerData[row]
}
}

It looks like a bug in Mac Catalyst. Try using the UIPicker embedded in an UIActionSheet. ActionSheetPicker-3.0 is a ready-made solution. Show the ActionSheetPicker in textFieldDidBeginEditing of your UITextField.
