How to get text from programmatically added UITextView [Swift]

Iam adding textFields with this code to add 3 UITextFields to ViewController:

for var index = 0; index < 3; ++index {
    var textField = UITextField(frame: CGRectMake(0, 0, 300, 40))
    var pom:CGFloat = 130 + CGFloat(index*50)
    textField.center = CGPointMake(185, pom)
    textField.layer.borderWidth = 1.0;
    textField.layer.cornerRadius = 5.0;
    textField.textAlignment = NSTextAlignment.Center
    self.view.addSubview(textField)
}

and now i need to get text from all textFields. Can someone tell me, how can i make it?

You could store them in an array, set the tag property on each one with the value of the counter in your loop, then retrieve them by that tag later on:

class MyViewController: UIViewController {

    var textFields = [UITextField]()

    override func viewDidLoad() {
        super.viewDidLoad()

        for var index = 0; index < 3; ++index {
            var textField = UITextField(frame: CGRectMake(0, 0, 300, 40))
            var pom:CGFloat = 130 + CGFloat(index*50)
            textField.center = CGPointMake(185, pom)
            textField.layer.borderWidth = 1.0;
            textField.layer.cornerRadius = 5.0;
            textField.textAlignment = NSTextAlignment.Center
            textField.tag = index
            self.textFields.append( textField )
            self.view.addSubview(textField)
        }

        for var index = 0; index < 3; ++index {
            if let textField = self.textFieldForTag( index ) {
                print( textField.text )
            }
        }
    }

    func textFieldForTag( tag: Int ) -> UITextField? {
        return self.textFields.filter({ $0.tag == tag }).first
    }
}
