NSURL Throws nil exception using mailto:

Question

I was trying to open mail on UILabel click event. But its throws fatal error:

unexpectedly found nil while unwrapping an Optional value.

Code used:

func sendMail(sender:UITapGestureRecognizer){
        print("mail::" + self.lblMail.text!) // joe@nts.com is here
        let url = NSURL(string: "mailto:\(self.lblMail.text)")! //url is nil when debugged
        UIApplication.sharedApplication().openURL(url)
    }

Check to make sure self.lblMail.text is non-nil before proceeding by unwrapping it with an if let:

if let email = self.lblMail.text {
    let url = NSURL(string: "mailto:\(email)")!
    UIApplication.sharedApplication().openURL(url)
}

If you get the error:

LaunchServices: ERROR: There is no registered handler for URL scheme mailto

Make sure you're running this code on an actual device and not the iOS Simulator.

Try let url = NSURL(string: "mailto:\(self.lblMail.text!)")!

it shows ERROR: There is no registered handler for URL scheme mailto, Is it because I m using a simulator instead of a device – user2695433 Feb 25 '16 at 14:37
but it doesn't crash where it used to, does it? – Andrey Chernukha Feb 25 '16 at 14:39
yes, I think this is because of simulator usage. the device should handle such an url – Andrey Chernukha Feb 25 '16 at 14:40
