Moya Tutorial for iOS: Getting Started

30 mins

Taking Moya to the Next Level

Moya is an extremely versatile networking library with too many additional features to fully cover in this tutorial, but they are definitely worth mentioning:

  1. Reactive Extensions: Moya provides and maintains two excellent reactive additions to Moya for RxSwift and ReactiveSwift, aptly named RxMoya and ReactiveMoya.
  2. Plugins: Moya lets you create pieces named Plugins, which you can use to modify requests and responses, or to perform side effects. The can be useful, for example, for logging requests and responses or automatically showing a network activity indicator when running network requests.
  3. Testing: As mentioned earlier, every TargetType has a sampleData property wherein you can provide a stubbed response for your endpoints. When creating a MoyaProvider, you can provide a stubClosure, which defines if you want Moya to return a stubbed response or a real one (the default). You can learn much more about this in Moya’s testing documentation.
  4. Harvey: Speaking of stubbing responses — some of the team behind Moya are developing a separate framework named Harvey for easy mocking of network responses. It is still in early development but I’d highly recommend following this project.
