MoyaUnbox

Unbox mappings for Moya network requests, includes ReactiveCocoa and RxSwift support.

Installation

Carthage

Add github JaviLorbada/MoyaUnbox to your Cartfile.

Carthage will build three frameworks, MoyaUnbox, RxMoyaUnbox and ReactiveMoyaUnbox, once then just import the one you need depends on your preference.

Usage

Unbox Model

First you need to create your model, for example a GitHub user based on their user API.

struct GHUser {
  let login: String
  let identifier: Int
  let avatarURL: NSURL
  …
}

extension GHUser: Unboxable {
  init(unboxer: Unboxer) {
    self.login = unboxer.unbox("login")
    self.identifier = unboxer.unbox("id")
    self.avatarURL = unboxer.unbox("avatar_url")
    …
  }
}

Then you need do the mappings.

1. Moya

After you create your own API provider like

let provider = MoyaProvider<GitHubAPI>(plugins: [NetworkLoggerPlugin(verbose: true)])

you could use mapObject and mapArray for the response:

provider.request(.UserProfile("octocat"),   
completion: { result in
	do {
	  if let user = try result.value?.mapObject(GHUser) {
	    print("User: \(user)")
	  } else {
	    print(result.error)
		}
	} catch {
	  print(error)
	}
})

2. RxSwift

If you use Moya RxSwift extensions, you can use RxMoyaUnbox extension.

 provider.request(.UserProfile("JaviLorbada"))
    .filterSuccessfulStatusCodes()
    .mapObject(GHUser)
    .observeOn(MainScheduler.instance)
    .subscribe(onNext: { user in
      print("User: \(user)")
    }, onError: { error in
	    print(error)
    })
    .addDisposableTo(disposeBag)

3. ReactiveCocoa

If you use Moya ReactiveCocoa extensions, you can use ReactiveMoyaUnbox extension.

 provider.request(.UserProfile("JaviLorbada"))
    .filterSuccessfulStatusCodes()
    .mapObject(GHUser)
    .observeOn(UIScheduler())
    .startWithResult { result in
    if let user = result.value {
      print("User: \(user)")
    } else { 
	    print(result.error)
    }
  }
