UITextfield delegate method not getting called when text set programatically

Question

My UIViewController confirms to UITextFieldDelegate and implements delegate method:

func textFieldDidEndEditing(_ textField: UITextField)

It also sets delegate = self in viewDidLoad All works fine when user enters text from keyboard. However, the above delegate method is not called when I set text programatically. i.e textField.text = "some text"

I have also tried calling textField.sendActions(for: .editingDidEnd). Please note that I need to trigger this delegate method while writing unit tests for my controller.

This method is called after the text field resigns its first responder status.Setting the text property in code does not change the status of the first responder. — vadian

All this does is describe the (correct) behavior. What's the question? — matt

To be specific, question is that why textField.sendActions(for: .editingDidEnd) method is not causing to trigger the delegate method "func textFieldDidEndEditing(_ textField: UITextField)" — Ali Jawad

Delegate methods respond to user input only. you need to manually call the delegate methods after setting the text.

From Apple documentation for textFieldDidEndEditing:

"This method is called after the text field resigns its first responder status."

You are changing the value of textField, not resigning it.

You could add an observer for textDidChangeNotification, which will notify you when text value is changed. Refer to point 4

I want the delegate method to be triggered "func textFieldDidEndEditing(_ textField: UITextField)", when text is set programatically. How can i forcibly trigger that?
