Ability to cancel request with Swift implementation

[cjolif]

Except if I'm mistaken I don't see a way to cancel an API call on the generated Swift/iOS code.

I believe you're referring to https://github.com/Alamofire/Alamofire#request and I don't think we have implemented the support for cancel yet.

PetstoreClient|master⚡ ⇒ grep -R -i cancel *
PetstoreClient|master⚡ ⇒ 

Is that something you've cycle to contribute?

@wing328 yes that's what I had in mind.

maybe but I first need to better understand the generated Swift request API and see if there are not other things that are even more problematic on my side and I would better concentrate on.

I also need a cancelable request. My suggestion is to create a protocol Cancelable and hide a cancelation logic inside it:

public protocol Cancelable { func cancel() }

Then add a cancelable property to RequestBuilder:
var cancelable: Cancelable?
Finally, assign a cancelable = AlamofireCancelable(request: request) when request is ready in processRequest. Where AlamofireCancelable is Alamofire specific request cancellation.

So to cancel a request user would have to hold a reference to RequestBuilder and check if cancelable is not nil (meaning that request has started, so it can be cancelled):
if let cancelable = requestBuilder.cancelable { cancelable.cancel() }

If that approach is OK, I could create a PR.
