How to make phone call in iOS 10 using Swift? [duplicate]

You can call like this:

 if let url = URL(string: "tel://\(number)") {     UIApplication.shared.openURL(url) }

For Swift 3+, you can use like

guard let number = URL(string: "tel://" + number) else { return }UIApplication.shared.open(number)

OR

UIApplication.shared.open(number, options: [:], completionHandler: nil)

Make sure you've scrubbed your phone number string to remove any instances of (, ), -, or space.

In Swift 4.2

func dialNumber(number : String) { if let url = URL(string: "tel://\(number)"),   UIApplication.shared.canOpenURL(url) {      if #available(iOS 10, *) {        UIApplication.shared.open(url, options: [:], completionHandler:nil)       } else {           UIApplication.shared.openURL(url)       }   } else {            // add error message here    }}

Call this like below

dialNumber(number: "+921111111222")

Hope this help.
