☑️ Designing iOS architecture: Checklist

List of questions one should ask while designing an architecture.

The article explaining the motivation is here.

📈Is it scalable?

  • Does it handle changing business requirements efficiently?
  • Does it support gradual adoption in existing projects?
  • Does it allow replacing third-party components easily?
  • Does is encourage composition of small independent components?
  • Does it allow adding UI to features later?
  • Does it support breaking of retain cycles on integration rather than component level?
  • Does it support people working simultaneously on different parts of a feature?
  • Does it limit the use of event/notification systems to specific layers?
  • Does it provide a strategy for cutting corners and tech debt?

🚧Is it maintainable?

  • Does it provide a tactic for fighting massive objects?
  • Does it limit the number of dependencies for an object?
  • Does it try to reduce the amount of boilerplate code?
  • Does it minimize the number of different roles of components?
  • Does it suggest project structure tolerant to changes?
  • Does it feel right?

🔱Is it prepared for navigation?

  • Does it explain how to pass data between components?
  • Does it allow describing and discovering app flow naturally?
  • Does it avoid transient dependencies?
  • Does it define how to store state?
  • Does it minimize the amount of global state?
  • Does it allow opening a stack of screens?
  • Does it handle opening of a screen from a push notification?

🌟Is it promoting quality?

  • Does it maximize the amount of testable code?
  • Does it encourages compile-time decisions over runtime decisions?
  • Does it avoid force casting and unwrapping?
  • Does it allow stubbing asynchronous code to run tests synchronously?
  • Does it support testing of UI?
