I have an application that needs to make a USSD call, but on some devices the * and # don't work on the dialer, on others it does.
if let phoneNumber = ussdNumberTextfield.text {
let encoded = "telprompt:\(phoneNumber)".addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!
if let url = URL(string: encoded) {
if application.canOpenURL(url){
DispatchQueue.main.async {
self.application.open(url, options: [:]) { success in
}
}
}
}
}
