Swift Best Practices

This skill equips AI agents with Swift coding standards and best practices, ensuring generated code is clean, efficient, and idiomatic for Apple platforms. It helps agents avoid common pitfalls in iOS and macOS development while adhering to modern language conventions.

When to use it

• Refactoring legacy Objective-C or early Swift codebases into modern syntax.
• Generating new SwiftUI views that strictly follow current design patterns.
• Auditing existing projects for memory management issues or concurrency errors.
• Creating unit tests that align with XCTest best practices.

Key capabilities

• Enforces modern Swift 5+ language features and syntax rules.
• Applies Apple-specific architectural patterns like MVVM and Clean Architecture.
• Generates type-safe, crash-free code optimized for iOS and macOS performance.
• Ensures adherence to accessibility guidelines within UI implementations.

Example prompts

• "Refactor this legacy Swift class to use modern async/await patterns and property wrappers."
• "Generate a SwiftUI view for a settings page that follows Apple's Human Interface Guidelines."
• "Audit this codebase for common memory leaks and suggest fixes using Combine or Actors."

Tips & gotchas

Ensure your AI agent has access to the latest Xcode SDKs, as Swift best practices evolve rapidly with each major release. This skill is most effective when paired with a project that already uses a standard build system like Swift Package Manager or CocoaPods.
