☑️ 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 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 provide a strategy for cutting corners and tech debt?

🚧Is it maintainable?

• [ ] Does it provide a tactic for fighting massive objects?
