iOS Architecture — Advanced

Use When

• Expert iOS app architecture patterns — dependency injection containers with scoped lifetimes, MVVM navigation via state enums, Redux/unidirectional data flow, Elements architecture, use case factory protocols, and Observer composition. Use when...
• The task needs reusable judgment, domain constraints, or a proven workflow rather than ad hoc advice.

Do Not Use When

• The task is unrelated to ios-architecture-advanced or would be better handled by a more specific companion skill.
• The request only needs a trivial answer and none of this skill's constraints or references materially help.

Required Inputs

• Gather relevant project context, constraints, and the concrete problem to solve; load references only as needed.
• Confirm the desired deliverable: design, code, review, migration plan, audit, or documentation.
