In Xcode, the code that works in Playground does not run properly in the CommandLineTool project.

import Foundation

Let url=URL (string: "https://api.github.com/users/( hidden characters)"!
let get = URLSession.shared.dataTask(with:url, completionHandler: {data, response, error in)
    iflet error = error {
        print(error.localizedDescription)
        return
    }

    guard let data = data,
          let response = response as ?HTTPURLResponse else {
        print("data or response is nil")
        return
    }

    if response.statusCode==200 {
        print(String(data:data, encoding:.utf8))
    } else{
        print("statusCode:\(response.statusCode)")
    }
})

get.resume()
