Alamofire Serial Requests
<p>I need the requests to be executed in order, although this is not working using Alamofire.</p>

<p>I want to print 1 to 30 in sequence (assuming the response is just an echo for the parameter)</p>

<pre><code>// Only 1 connection per Host

let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
configuration.HTTPMaximumConnectionsPerHost =  1
configuration.timeoutIntervalForRequest = 30
self.manager = Alamofire.Manager(configuration: configuration) 

for i in 1...30 {
    manager.request(.GET, "http://httpbin.org/get", "i" : i], encoding: .JSON)
        .responseJSON { response in
            switch (response.result){
            case .Failure(let error):
                print("error")
                break;
            case .Success(let json):
                print(json)
            }
     })
</code></pre>
