I'm trying to implement sending of SMS in my app. I want to try this via a 3rd party. So I need to make a HTTP GET request for sending the SMS:

Code Block https://sveve.no/SMS/SendMessage?user=*&passwd=*&to=***&msg=Meldingstekst&f=json

I tried this:

Code Block  let url = URL(string: "https://sveve.no/SMS/SendMessage?user=myUser&passwd=myPassword&to=12345678&msg=This is the message text&f=json")!
let task = URLSession.shared.dataTask(with: url) {(data, response, error) in
guard let data = data else { return }
print(String(data: data, encoding: .utf8)!)
}
task.resume()

Fatal error: Unexpectedly found nil while unwrapping an Optional value

The error is on the URL. What can be the issue?

Each parameter in a URL needs to be properly escaped. Better try using URLComponents:

Code Block var myUser: String = "myUser"
var myPassword: String = "myPassword"
var msg: String = "This is the message text"
var urlComponents = URLComponents(string: "https://sveve.no/SMS/SendMessage")!
urlComponents.queryItems = [
    URLQueryItem(name: "user", value: myUser),
    URLQueryItem(name: "myPassword", value: myPassword),
    URLQueryItem(name: "msg", value: msg),
    URLQueryItem(name: "f", value: "json"),
]
let url = urlComponents.url!
print(url) //->https://sveve.no/SMS/SendMessage?user=myUser&myPassword=myPassword&msg=This%20is%20the%20message%20text&f=json
