How to clear the text field automatically

I have a question about UITextField() in Swift. How can I clear the text in the text field when I click on it?

My textField.text = "0". I want to automatically remove the number "0" when I click on the text field:

import UIKit
class ViewController: UIViewController, UITextFieldDelegate {

    @IBOutlet var lbltext: UILabel!
    @IBOutlet var scrolview1: UIScrollView!
    @IBOutlet var fi: UITextField!
    @IBOutlet var scrolviewus: UIScrollView!
    @IBOutlet var counterLabel: UILabel!
    override func viewDidLoad() {
        super.viewDidLoad()
        fi.text = "0"
       }

       override func didReceiveMemoryWarning() {
         super.didReceiveMemoryWarning()
         // Dispose of any resources that can be recreated.
       }

       @IBAction func button(sender: AnyObject) {
        lbltext.numberOfLines = 0
        lbltext.text! = lbltext.text! + "\n" + fi.text! + "\n" + "---  "
    }
 }

Use a small button on the right corner of textfield. Create action of that button.

@IBAction func removeSearchTFTapped(_ sender: Any) {
    searchTF.text = ""
}

You can easily clear the TextField in swift

emailTextField.text?.removeAll()

Use this method,

If you want to manually clear the text field use this code:

textField.text = ""

If you want the text field to empty when you begin editing, use the delegate method below:

func textFieldDidBeginEditing(textField: UITextField) {
    textField.text = ""
}

If you are using multiple text fields, use the method below:

func textFieldDidBeginEditing(textField: UITextField) { 
    if (textField == oneTextField) {
       textField.text = ""
    } 
    else if (textField == anotherTextField) {
       // Perform any other operation
    } 
}

func textFieldDidBeginEditing(textField: UITextField) {
        fi.text = ""
    }

func textFieldDidEndEdition(textField: UITextField) {

     if fi.text isEqualToString:@"" {
          fi.text = @""
     }

}

Simply use textFieldDidBeginEditing method to handle focus change, and clear text.

func textFieldDidBeginEditing(textField: UITextField) {
    textField.text = ""
}

There are a couple of ways you can solve this problem, depending on what you're looking for. The first is to use a placeholder instead of setting the text to 0. A placeholder will disappear whenever the user starts typing and reappear if they type nothing in:

fi.placeholder = "0"

if you want the 0 to be the value and not just a placeholder, there are lots of built in methods to track editing/entering/returning/etc of a textfield. This does require implementation of the UITextFieldDelegate however, which it appears you have already done.

var isFirstTime = true

override viewDidLoad() {
     super.viewDidLoad()
     fi.delegate = self
}

func textViewDidBeginEditing(textView: UITextView) {
    isFirstTime = false
    if fi.text == "0" {
        fi.text = ""
    }
}

func textViewDidEndEditing(textView: UITextView) {
    if fi.text.isEmpty {
        fi.text = "0"
        isFirstTime = true
    }
}

The is first time var is only present so that the user can type 0 if they choose. If the user should not be able to type 0, then it may be removed.
