Alamofire callback after multiple requests finish

I have to make a number of async requests to a server (let's say 20) and I need to wait for all them to finish (being successful or not) to trigger an action. I want to know if there's an elegant way of keeping a reference to all of them without keeping a variable in the parent's scope, i.e not like:

var numberOfCalls = 10

for i in 1...20 {
    Alamofire.request(.GET, url) { response in 
        numberOfCalls--
        if numberOfCalls == 0 {
             // do something
        }
    }
}

I'm using Alamofire, Swift 2, xcode 7

I finally wrapped my head around GCD handling multiple concurrent tasks on this post Dispatch Groups suggested by @GoodSp33d
