State Pattern (SwiftUI)

Select local vs shared state and implement the pattern with best practices.

When to Use

  • •When state is shared across multiple views or flows.

Inputs

  • •State shape and lifecycle
  • •Consumers and update frequency
  • •Persistence or caching needs

Instructions

  1. •Decide local (@State) vs shared (@StateObject, @Observable, @Environment).
  2. •Use a view model for shared state.
  3. •Add derived state helpers in view models.
  4. •Add tests for state transitions.

Output

  • •State implementation with tests and a short rationale.
