For Loop - Alamofire Requests in a synchronous way Swift4 - Execute for loop waiting till async request returns

Question

for i in 0 ..< 5 {
                print("Request Number" ,i)
                Alamofire.request("https://httpbin.org/get", parameters: ["foo": "bar"]).responseJSON { response in
                    print("Finished request \(i)")
                }
            }

In this sample of code, is there any way I can get the above code run in a way such that it prints

Request Number 0
Finished request 0
Request Number 1
Finished request 1
Request Number 2
Finished request 2
Request Number 3
Finished request 3
Request Number 4
Finished request 4

@Hardik can you explain how much delay? We can't assume when server response for a request. — Mahendra, Jun 01 '18 at 09:35

try this code

for i in 0 ..< 5 {
            print("Request Number" ,i)
            let runLoop = CFRunLoopGetCurrent()
            Alamofire.request("https://httpbin.org/get", parameters: ["foo": "bar"]).responseJSON { response in
                print("Finished request \(i)")
                CFRunLoopStop(runLoop)
            }
            CFRunLoopRun()
        }
