I've been trying to access Data from a Website via Swift. To see where the problem is I put these print()'s in there. "1" is getting printed every time, but "2" isn't.

import Foundation

func getData()
{
    guard let url = URL(string: "https://jsonplaceholder.typicode.com/posts") else {return}

    print("1");

    let session = URLSession.shared.dataTask(with: url)
    {
        data, response, error in

        print("2");

        if let error = error {
            print("THere was an error: \(error.localizedDescription)")
        }
        else{
            let jsonRes = try? JSONSerialization.jsonObject(with: data!, options: [])
            print("The response: \(jsonRes)")
        }
    }.resume()
}

getData();

Try removing `let session =` to simply call resume() without the assignment to a variable. – Viggo Lundén Apr 12 '22 at 12:11
Na, didn't work. Still nothing – JokoFlex Apr 12 '22 at 12:16
How do you execute this code, in an playground or as part of an app or command line tool? This code executes fine for me in a playground printing 1, 2 and the response – Joakim Danielson Apr 12 '22 at 12:24
You could try the URL, its fine. It's only a bunch of JSON Data. I execute the whole thing in just a Xcode command line tool. Basically a terminal – JokoFlex Apr 12 '22 at 12:26
So maybe the command line tool exits before you get the response. – Joakim Danielson Apr 12 '22 at 12:27
should I try it in a playground then? – JokoFlex Apr 12 '22 at 12:27
Jup, it works now. thx – JokoFlex Apr 12 '22 at 13:47
