Answer 1

(Swift 3) Add text box and uipickerview to the storyboard then add delegate and data source to uipickerview and add delegate to textbox. Follow video for assistance https://youtu.be/SfjZwgxlwcc

import UIKit  class ViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource, UITextFieldDelegate {      @IBOutlet weak var textBox: UITextField!     @IBOutlet weak var dropDown: UIPickerView!      var list = ["1", "2", "3"]      public func numberOfComponents(in pickerView: UIPickerView) -> Int{         return 1     }      public func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{          return list.count     }      func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {          self.view.endEditing(true)         return list[row]     }      func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {          self.textBox.text = self.list[row]         self.dropDown.isHidden = true     }      func textFieldDidBeginEditing(_ textField: UITextField) {          if textField == self.textBox {             self.dropDown.isHidden = false             //if you don't want the users to se the keyboard type:              textField.endEditing(true)         }     } }

A 'drop down menu' is a web control / term. In iOS we don't have these. You might be better looking at UIPopoverController. Check out this tutorial for a bit of an insight to PopoverControllers
