Hey Arman! Here is what an action function from a button in swift that will call a number, the inside section UIApplication will work if attached to a label, but for simplicity this is an action function from a button.

@IBAction func callButton(sender: AnyObject) {
      UIApplication.sharedApplication().openURL(NSURL(string: "tel://1234567890"))
}

Hope this helps you!

Hi, Ryan. Thanks for answers. Is it callable from iOS Simulator? Because I can't make call from simulator

Unfortunatley you cannot test this on the simulator because the simulator doesn't have any phone functionality, but testing it on a device, as I did, will work!

Well UILabel's do not have any default touch interaction behavior, but you can monitor the touches on the screen and check if that touch is in the frame of the label! 

let phoneNumberLabel:UILabel = UILabel(frame: CGRectMake(85, 220, 120, 45))

    override func viewDidLoad() {
        super.viewDidLoad()
        phoneNumberLabel.bounds = CGRectMake(CGRectGetMidX(self.view.frame), 220, 120, 45)
        phoneNumberLabel.text = "Call Number"
        self.view.addSubview(phoneNumberLabel)
    }

    override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
        for touch: AnyObject in touches {
            let location = touch.locationInView(self.view)
            if CGRectContainsPoint(phoneNumberLabel.frame, location) {
                UIApplication.sharedApplication().openURL(NSURL(string: "tel://1234567890"))
            }
        }
    }

This is a complete application that can be pasted into a single view application template and experimented with, I hope this helps you!
