Which Swift frameworks are incompatible with WebAssembly?

Frameworks that rely on native Apple UI or hardware-specific features are usually incompatible, including UIKit, SwiftUI, CoreGraphics, CoreML, and URLSession.

Will porting to Wasm break my existing iOS or macOS code?

No. The skill uses conditional compilation (#if os(WASI)) to ensure that Wasm-specific changes only apply to the WebAssembly build while keeping original implementations intact.

How does this skill handle Accelerate library functions?

It suggests replacements such as the Matft library, CLAPACK, SIMD, or pure Swift implementations to ensure mathematical operations work on Wasm environments.

What happens if an API is fundamentally incompatible with Wasm?

When code cannot be ported due to technical limitations, the skill helps you create a Swift protocol to map the public API and inject the implementation as a dependency.

Mobile Development

Ports and refactors Swift applications for WebAssembly compatibility using automated framework analysis and conditional compilation.

The Swift Wasm Porting skill is a specialized tool for developers looking to bring Swift codebases to the web. It analyzes packages for platform-specific dependencies like UIKit or CoreML, identifies incompatible APIs, and automates the refactoring process using conditional compilation patterns. By providing Wasm-safe alternatives for libraries like Accelerate and integrating directly with the Swift Wasm toolchain, this skill streamlines the transition from native Apple platforms to high-performance WebAssembly environments while maintaining cross-platform source code integrity.
