To create a dropdown using tableview and popover was little bit time consuming work but luckily we have an alternative solution for that use this library very easy to use

Initialization:

let dropDown = DropDown()

// The view to which the drop down will appear on
dropDown.anchorView = view // UIView or UIBarButtonItem

// The list of items to display. Can be changed dynamically
dropDown.dataSource = ["Car", "Motorcycle", "Truck"]

Handle selection:

// Action triggered on selection
dropDown.selectionAction = { [unowned self] (index: Int, item: String) in
  print("Selected item: \(item) at index: \(index)")
}

// Will set a custom width instead of the anchor view width
dropDownLeft.width = 200

Display actions:

dropDown.show()
dropDown.hide()

Hope this will help you
