Check for changes in UITextField

I'm attempting to make an app that checks the text in a UITextField and does something in response to what is written in it. I could possibly have the user type their input and then press a button. I want to be able to check the text field constantly without the application becoming unresponsive.

What you have to do is to attach an IBAction to your UITextField Sent Events Editing Changed:

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var strLabel: UILabel!

    override func viewDidLoad() {
        super.viewDidLoad()
    }
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
    @IBAction func editingChanged(sender: UITextField) {
        strLabel.text = sender.text
    }
}
