Edit 2 labels from 1 text field

Good day! So here is my issue - I need to change 2 different labels from 1 text field. Tried simple if-else logic, but it didn't work in my case.

    func labelTextChanger() {

    if fromUserName.text == nil {
        fromUserName.text = textFileld.text
    } else  {
        replyToUserName.text = textFileld.text
    }
}

ma case

So here is right code for ma case:

var zalupa = Bool()


func textFieldShouldReturn(textField: UITextField) -> Bool {
    if (!zalupa) {
        fromLabel.text = textField.text
        zalupa = true
    } else {
        replyLabel.text = textField.text
        zalupa = false
    }
    return true
}

You don't need the else if you want to update both labels together.

if fromUserName.text == nil {
    fromUserName.text = textFileld.text
    replyToUserName.text = textFileld.text
}

A very broad example of an implementation you could use. Basically you should use the UITextFieldDelegate. When a user finishes editing the textfield a call to textFieldDidEndEditing: will be made and in this function you can update your labels.

import UIKit

class ViewController: UIViewController, UITextFieldDelegate {

    var labelOne = UILabel()
    var labelTwo = UILabel()
    var myTextField = UITextField()

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    func textFieldDidEndEditing(textField: UITextField) {
        if textField == myTextField {
            labelOne.text = textField.text
            labelTwo.text = textField.text
        }
    }
}

If I understand your question correctly, you need to change the text of 2 UILabels whenever you editing the UITextField? If so, you should use the "Editing Began" or "Editing Changed" IBAction linked with your storyboard file. Then, have the UILabel's value change to whatever the UITextField's text is.

@IBAction textFileIdEditingChanged {
    fromUsername.text = textFileId.text
    replyToUserName.text = textFileId.text
}

it seems fromUserName.text is an empty string so you should change to :

  func labelTextChanger() {

    if fromUserName.text != "" {
        fromUserName.text = textFileld.text
    } else  {
        replyToUserName.text = textFileld.text
    }
}

Try this one,

  func labelTextChanger() {

        if fromUserName.text?.characters.count > 0 {
            fromUserName.text = textFileld.text
        } else  {
            replyToUserName.text = textFileld.text
        }
    }

Because it will return nil only when it's not exists in memory. so, it can't be nil.
