What is wrong in my function to make a call

Question

this is my code to make a phone call

let phoneCall = phoneNumberTF.text
        if let phoneCall = phoneCall {
            let url = NSURL(string: "tel://\(phoneCall)")
            UIApplication.sharedApplication().openURL(url!)

        }else {
            let alert = UIAlertController(title: "Error", message: "not correct phone", preferredStyle: .Alert)
            let action = UIAlertAction(title: "Retry", style: .Default, handler: nil)
            alert.addAction(action)
        }

I'm getting this error in the log

ERROR: There is no registered handler for URL scheme tel

Are you testing on a real device? You can't make calls in the simulator. — rmaddy, Nov 05 '15 at 22:02
@rmaddy oh really i can't even open the controller that makes the phone call? — Marco Dinatsoli, Nov 05 '15 at 22:04
The error message is coming from the call to `openURL`. That will fail on the simulator because there is no phone on the simulator. — rmaddy, Nov 05 '15 at 22:06
Try changing `tel://` to `telprompt://` Also it only works on an actual phone. — Senõr Ganso, Sep 28 '16 at 15:10

the correct url scheme is something like tel:PHONE_NUMBER (without the slashes you included). you should also check if the application CAN open the url you provide by calling UIApplication.sharedApplication.canOpenURL()...

let phoneNumber = "123-456-789"
let phoneURL = NSURL(string: "tel:\(phoneNumber)")!
if UIApplication.sharedApplication().canOpenURL(phoneURL) {
  UIApplication.sharedApplication().openURL(phoneURL)
}

Per Apple docs https://developer.apple.com/library/ios/featuredarticles/iPhoneURLScheme_Reference/PhoneLinks/PhoneLinks.html

The correct format is tel:. So first change that and then you should check if the UIApplication.sharedApplication.canOpenURL() before doing it. If you're running on a simulator it will not work.

can i install the app for making the calls on the simulator ? – Marco Dinatsoli Nov 05 '15 at 22:09
@MarcoDinatsoli No you would need to run this on a real device. – Peter Foti Nov 05 '15 at 22:10
