Swift wait for closure thread to finish

Question

I\'m using a very simple swift project created with SPM where it includes Alamofire.

main.swift:

import Alamofire

Alamofire.request(\"https://google.com         


        

Answer 1

For Swift 3

let group = DispatchGroup()
group.enter()
DispatchQueue.global(qos: .userInitiated).async {
    // Do work asyncly and call group.leave() after you are done
    group.leave()
}
group.notify(queue: .main, execute: {
    // This will be called when block ends             
})

This code will be helpful when you need to execute some code after some task is done.
