I have a NSTextField where I would like to enter text at the insertion point. I have a code that don't generate errors:

    let str = "Abc" 
    myTextField.insertText(str)

[edit] When, in the field there is 123|45 (the "|" represents the text insertion point), the output should be 123Abc|45.

Unfortunately don't work because it's deprecated. Here is the documentation. What is the replacement?

Please note that this question is for NSTextField not NSTextView, which has a question here: NSTextView's insertText method is deprecated in OS X v10.11. What is the replacement?

Why don't you read comments posted at stackoverflow.com/questions/32787814/… ? – El Tomato
Hi El Tomato, actually I read the comment by bhaller: "With an NSTextField you would need to work with the field editor of the textfield, which is an NSTextView" But to be honest I don't understand it. – Cue
@Cue , what is the the expected output do you need insertText when myTextField already has 44 ? – Rajamohan S
Hi RAJAMOHAN-S, when the i-beam is between 4 and 4, the output should be 4Abc|4. – Cue

Get the field editor for the window that the text field is in, then use insertText(_:, replacementRange:) on that:

let textfield = NSTextField()...
if let fieldEditor = textfield.window?.fieldEditor(false, for: textfield) as? NSTextView {
    fieldEditor.insertText("abc", replacementRange: fieldEditor.selectedRange())
}

To clarify: this requires that the text field has input focus. If some other field has input focus the field editor will insert text there instead.

If your textField has focus (is first responder) then any responder method like insertText: or inserText:replacementRange: will do the job. Problem is when you want to make the textField first responder (it will lose/reset the selectionRange).

func appendText(_ text: String, for textField: NSTextField) {
    makeFirstResponder(textField)
    if let fieldEditor = (textField.currentEditor() as? NSTextInputClient) {
        fieldEditor.insertText(text, replacementRange: fieldEditor.selectedRange())
    }
}

func makeFirstResponder(_ textField: NSTextField) {
    if textField.window?.firstResponder != textField.currentEditor() {
        textField.window?.makeFirstResponder(textField)
        if let length = textField.currentEditor()?.string.count {
            textField.currentEditor()?.selectedRange = NSMakeRange(length, 0)
        }
    }
}
