It wasn´t hard. We needed to reimplement/copy a few things that were taken for granted in AFNet such as user agent, accept and other headers. Those were easy to do with NSURLSessionConfiguration.

In terms of request and url construction they are created by each model doing the request, it is a bit more of code and maybe duplicated but explicit as there is no implicit baseURL. The query/body is also constructed in place being explicit and not having to worry if the serializer is JSON or form data. Also it has the advantage of performance since the request serializer of AFNetworking creates mutable copies the request around a lot to do checks in methods that take immutable ones.

Also I created this category for convenience

@interface NSMutableURLRequest (JSONBody)

- (void)setJSONBody:(id)body;
- (BOOL)setJSONBody:(id)body options:(NSJSONWritingOptions)options error:(NSError **)error;

/*
Basically what we are going to do is use and profit from NSURLRequests being conformant to NSCoding, 
and a little known API from NSURLProtocol which allows us attach info to requests.
*/

//Step 0: For the purpose of this gist, we'll already have a background session setup and assume a bunch of stuff.
NSURLSession *bgSession = [NSURLSession magicMethodWhichGivesMeTheAlreadySetupSession]; //Geeez, Methods are long in Obj-C.

//IMPORTANT: Request must be mutable in order for this to work. Got an immutable one. Make a copy. Can't? Well, Make it so!.
//Step 1: Setup your basic request.

#The GIF is dead

Nowadays when we use the word GIF, hardly it refers to the file format, rather we talk about a really short motion picture (often loopable) without sound.
We hardly think of the actual file format used to display these (unless it takes too long to load, then it surely is a G.I.F.)

As such I think we can at last please Steve Wilhite and give him the pronunciation he always wanted by introducing this separation of concepts apt for today:

G.I.F.: Graphics Interchangeable Format. This file format was originally preferred to deliver animated short movies on the internet (Pronounced with a J)
GIF: Short (often loopable) motion picture without sound (This one is pronounced with a hard G)

Just came across a weird issue where my app would be handed production push tokens while all the metadata of the compiled app indicated it was in a development environment.
Compiling said app with Xcode 7 (no code nor project changes) makes everything work as expected

      return Measurement(value: value * 3 / 10, unit: otherUnit)
