I&#39;m looking for a good pattern with which I can chain multiple HTTP requests. I want to use Swift, and preferrably [Alamofire][1].

Say, for example, I want to do the following:

1. Make a PUT request
2. Make a GET request
3. Reload table with data

It seems that the concept of [promises][2] may be a good fit for this. [PromiseKit][3] could be a good option if I could do something like this:

    NSURLConnection.promise(
        Alamofire.request(
            Router.Put(url: &quot;http://httbin.org/put&quot;)
        )
    ).then { (request, response, data, error) in
        Alamofire.request(
            Router.Get(url: &quot;http://httbin.org/get&quot;)
        )   
    }.then { (request, response, data, error) in
        // Process data
    }.then { () -&gt; () in
        // Reload table
    }

but that&#39;s not possible or at least I&#39;m not aware of it.

How can I achieve this functionality without nesting multiple methods?

I&#39;m new to iOS so maybe there&#39;s something more fundamental that I&#39;m missing. What I&#39;ve done in other frameworks such as Android is to perform these operations in a background process and make the requests synchronous. But [Alamofire is inherently asynchronous][4], so that pattern is not an option.
