See: https://freakycoder.com/ios-notes-31-how-to-hide-keyboard-by-touching-anywhere-cdf4f0c5151c

01. Create an extension

import UIKit
extension UIViewController {
    func hideKeyboardWhenTappedAround() {
     let tap: UITapGestureRecognizer =     UITapGestureRecognizer(target: self, action:    #selector(UIViewController.dismissKeyboard))
      tap.cancelsTouchesInView = false
      view.addGestureRecognizer(tap)
    }
    @objc func dismissKeyboard() {
       view.endEditing(true)
    }
}

02. Add this to viewDidLoad

// Hide Keyboard after tap is done
self.hideKeyboardWhenTappedAround()
