  • Uses Foundation’s JSONSerialization to transform responses

    • with content type of *​/json or *​/​*+json
    • to a dictionary or array
    • at the parsing stage.

    Disable this if you want to use a different parser, such as Swift 4’s JSONDecoder:

    let service = Service(
  baseURL: "https://example.com",
  standardTransformers: [.image, .text])  // no .json

let jsonDecoder = JSONDecoder()
service.configureTransformer("/foo") {
  try jsonDecoder.decode(Foo.self, from: $0.content)
}
