iOS Swift Recipes — App Store Production Patterns

Use When

• Production Swift recipes from real App Store apps. Covers safe numeric conversion, Codable tricks, custom decoders, type-safe Dictionary extraction, ISO 8601 dates, UIKit navigation/alerts/maps, UIView effects (shadows, gradients, blur), keyboard...
• 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-swift-recipes 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.
