SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Developers often need to maintain feature parity and a consistent UX across iOS, macOS, iPadOS, watchOS, tvOS, and visionOS. This Skill provides proven patterns to share business logic and UI components while isolating platform-specific differences.

Core Features & Use Cases

  • Shared code across Apple platforms via a single codebase and common abstractions.
  • Conditional compilation, platform-specific extensions, and adaptive UI patterns.
  • Use cases include building cross-platform libraries, multi-target apps, and UI that adapts per platform.

Quick Start

Create a Swift Package named SharedKit configured for all Apple platforms (iOS, macOS, iPadOS, watchOS, tvOS, visionOS). Implement a SharedKit module with platform checks using #if os(iOS)/macOS and provide a small example API to demonstrate cross-platform sharing. Build and run a minimal app on each target to verify shared logic is accessible and correctly compiled.

FAQPage Schema
How do I share Swift code across iOS, macOS, watchOS, tvOS, and visionOS?▼

Sharing Swift code across Apple platforms involves configuring a Swift Package for multiple targets and using conditional compilation directives like #if os(iOS) to isolate platform-specific logic while maintaining a single shared codebase.

What is the best way to use conditional compilation for multiplatform Xcode projects?▼

Conditional compilation in multiplatform Xcode projects is handled using platform checks like #if os(macOS) to separate platform-specific extensions and adaptive UI patterns, ensuring shared logic compiles correctly for each Apple target.

Can I maintain a single codebase for iOS and watchOS apps?▼

Yes, maintaining a single codebase for iOS and watchOS is possible by creating a shared Swift Package, applying platform availability checks, and isolating platform-specific differences to achieve feature parity across Apple devices.

Does Swift Package Manager support cross-platform Apple app development?▼

Swift Package Manager supports cross-platform Apple app development by allowing you to configure a shared module for iOS, macOS, iPadOS, watchOS, tvOS, and visionOS, managing dependencies and platform availability across all targets.

How do I build adaptive UI patterns for a multiplatform Swift app?▼

Building adaptive UI patterns for a multiplatform Swift app requires using shared abstractions for common components and conditional compilation to apply platform-specific extensions, ensuring the UI adapts correctly per platform.
