ios 10 Swift phone call is not initiated on some number

Question

I wrote some code to initiate phone call from String like the attached image. [function: phoneCallInitiation][1]

Some phone number can be initiated well with the format such as 02-123-1234, but some phone number with 031-123-1234 cannot be initiated but I can see phoneNumberString is working well.

Can u guess any reason to work like this?

func callButtonPressed () {
    let alertViewController = UIAlertController(title: NSLocalizedString("Call", comment: ""), message: "\(storeToDisplay.phoneNumber!)", preferredStyle: .alert)
    alertViewController.addAction(UIAlertAction(title: "Call", style: .default, handler: { (alertAction) -> Void in
        let phoneNumberString = "tel://\(self.storeToDisplay.phoneNumber!)"
        print("This is phonenumber: \(phoneNumberString)")
        if let url = URL(string: phoneNumberString) {
            UIApplication.shared.open(url, options: [:], completionHandler: nil)
        } else {
            print("WHAT Happenes")
        }
    }))
    alertViewController.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: { (alertAction) -> Void in
        alertViewController.dismiss(animated: true, completion: nil)
    }))
    present(alertViewController, animated: true, completion: nil)
}

I also tried remove '-' in the middle of phone numbers, but still the result is the same. Cannot initiate phone call — Junghoon Choi, Feb 20 '17 at 05:53

UIApplication only works or accepts if your number is ("1234567890"). So you need to remove " " and "-" from the string.

Hope below link will be helpful for you.

If you are using your application in simulator then you will not find anything happening. Try to run on actual device if you are using simulator.

try this

 let replaced = self.storeToDisplay.phoneNumber!.replacingOccurrences(of: "-", with: "")   
  let phoneNumberString = "tel://\(replaced)"

and add

if let url = URL(string: "telprompt://\(replaced)") {
                UIApplication.shared.open(url, options: [:], completionHandler: nil)
            }

else if you want to call direct

 if let url = URL(string: "tel://\(replaced)") {
                UIApplication.shared.open(url, options: [:], completionHandler: nil)
            }

Thanks for your help - sometimes it works when string includes '-' but better remove all. In my case, string contains blank in the last part so I did not recognize it. Thanks for your help! — Junghoon Choi, Feb 20 '17 at 06:12
