want to show UIPickerView in UIAlertController or UIPopoverController Swift?

Question

I want to show UIPickerView in UIAlertController or UIPopoverController, I am new to iOS, please give me some example code here.

I searched for them but can't find any satisfactory answers. I don't want to do it on UIActionSheet, because it is deprecated in iOS 9. Also I want it in Swift not in Obj-C. I tried the below example but it is not working for me.

Your Basic Code Look Like:

let alert = UIAlertController(title: title, message: message, preferredStyle: .actionSheet)
alert.isModalInPopover = true

//  Create a frame (placeholder/wrapper) for the picker and then create the picker
let pickerFrame = CGRect(x: 17, y: 52, width: 270, height: 100) // CGRectMake(left), top, width, height) - left and top are like margins
let picker = UIPickerView(frame: pickerFrame)

//  set the pickers datasource and delegate
picker.delegate = self
picker.dataSource = self

//  Add the picker to the alert controller
alert.view.addSubview(picker)

//Do stuff and action on appropriate object.

Please review below answer.

Is there any way to add UIPickerView into UIAlertController (Alert or ActionSheet) in Swift?
