What problem does it solve?

This Skill helps developers write more concise, readable, and robust Swift code by leveraging modern language features and patterns.

Core Features & Use Cases

• Modern Syntax: Utilize Swift 5.9+ if/switch expressions, Swift 6+ typed throws, and Never type for clearer control flow and error handling.
• Advanced Types: Understand and apply property wrappers, opaque (some) and existential (any) types, and result builders for cleaner APIs and DSLs.
• Data Handling: Implement best practices for Codable (including custom keys and decoding), modern collection APIs, and FormatStyle for type-safe formatting.
• Use Case: Refactor a complex conditional assignment into a single if expression, or implement a custom property wrapper to automatically validate user input.
