Custom Keyboard For textFIeld ( Swift 4)

• Use tap Gesture Recognizer in your viewcontroller, and add Action like this below

@IBAction func didTapScreen(_ sender: Any) {
        
  
        
    }

• First textField (textField1) setting Return Key --> Next

• Second textField (textField2) setting Return Key --> Done

• This full code in viewController.swift

import UIKit

class CustomKeyViewController: UIViewController, UITextFieldDelegate {

    @IBOutlet weak var textField1: UITextField!
    @IBOutlet weak var textField2: UITextField!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        textField1.delegate = self
        textField2.delegate = self
    }
    
    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        if textField1.isFirstResponder {
            textField2.becomeFirstResponder()
        } else {
            textField2.resignFirstResponder()
        }
        return false
    }
    
    // need item tap gesture recognizer
    @IBAction func didTapScreen(_ sender: Any) {
        
        if textField1.isFirstResponder {
            textField1.resignFirstResponder()
        } else if textField2.isFirstResponder {
