Implement a scaffold of a design system, where you can apply styles to UI elements. Given an example of badly designed code (Network service + View controller) fix it the way you want and implement missing callback action inside the VC. This task was seasoned with some delusional requirements, like what if token storage was not designed to be called multiple times and has to be initialised every time to avoid bugs? How would you implement dependency injection where you don't need to implement mocks with given protocols (some wise man told them to pass function closures instead). What is autorelease pool and how you can use it.
