Minimal example app to demo a the techniques below.

Struct-based dependencies

Inspired by Pointfree's course on Designing Dependencies I've decided to move away from a protocol-oriented approach for dependencies, and exposed a simple struct instead.

• separating interface and implementation can help a lot with build times in larger projects
• the approach results in less boilerplate, and provides straightforward inline mocking

Enum-based networking

This approach is based on Moya's implementation.

• enums are a good way to represent a finite number of endpoints
• the requirements of declaring a remote API are made clear via protocols.

Unit-testing networking code

Instead of wrapping Foundation components in protocols, I've decided to rely on URLProtocol to provide mock responses (based on this article)
