problem ：

I'm looking for a good pattern with which I can chain multiple HTTP requests. I am looking for a way to link multiple HTTP Good mode of request .I want to use Swift, and preferrably Alamofire . I want to use Swift, It is best to Alamofire .

Say, for example, I want to do the following: for instance , I want to do the following ：

1. Make a PUT request issue PUT request
2. Make a GET request issue GET request
3. Reload table with data Reload table with data

It seems that the concept of promises may be a good fit for this. It seems , The concept Commitment It may be a perfect fit for this .PromiseKit could be a good option if I could do something like this: If I could do something like this , PromiseKit It might be a good choice ：

NSURLConnection.promise(    Alamofire.request(        Router.Put(url: "http://httbin.org/put")    )).then { (request, response, data, error) in    Alamofire.request(        Router.Get(url: "http://httbin.org/get")    )   }.then { (request, response, data, error) in    // Process data}.then { () -> () in    // Reload table}

but that's not possible or at least I'm not aware of it. But it's impossible , Or at least I don't know .

How can I achieve this functionality without nesting multiple methods? How to implement this function without nesting multiple methods ？

I'm new to iOS so maybe there's something more fundamental that I'm missing. I am a iOS Novice , So maybe I lack something more basic .What I've done in other frameworks such as Android is to perform these operations in a background process and make the requests synchronous. I am here Android What other frameworks do is perform these operations in the background process and synchronize the requests .But Alamofire is inherently asynchronous , so that pattern is not an option. however Alamofire It's asynchronous in nature , So this model is not an option .
