Here’s a library from Ash Furrow created in Swift called Moya that utilizes AlamoFire providing a network abstraction layer that makes it easier to work with more complex APIs, especially those where an action can lead to different end points.

As the readme states some of the requirements for Moya that were met include:

  • Treat test stubs as first-class citizens.
  • Only allow endpoints clearly defined through Moya can be access through Moya, enforced by the compiler.
  • Allow iterating through all potential API requests at runtime for API sanity checks.
  • Keep track of inflight requests and don’t support duplicates.
