iOS Production Patterns

Use When

• Production-grade iOS patterns that separate good apps from great apps — UIViewController lifecycle gotchas, sensor lifecycle management, delegate pattern implementation, keyboard dismissal, Core Data migration, UIImagePickerController dismissal...
• 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-production-patterns 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.
