Dependency Injection

2021.12 Lightweight dependency injection and unit testing using async functions What if we could actually make our code fully testable in a way that doesn’t require us to introduce any new protocols, mocking types, or complicated abstractions? Let’s explore how we could make use of Swift’s new async/await capabilities to make that happen.

MVC

Apple’s MVC is not the same with traditional MVC, the main difference being that Apple does not allow the direct connection between view and model (this is assigned to the controller instead, which acts as the mediator). Whenever a cell updates itself using a model reference, the MVC pattern breaks (since this communication should have been done by the controller).
