What tools does this skill use?

The Swift Expert skill utilizes Read, Edit, and Grep tools to analyze and modify your Swift codebase effectively.

How does it handle SwiftUI performance issues?

It identifies anti-patterns like heavy computations in View bodies and suggests ways to extract logic into ViewModels or use proper property wrappers.

Does it support the new @Observable macro?

Absolutely; it includes clear mapping for migrating from the older ObservableObject and @Published pattern to the modern @Observable class syntax.

Can it fix SwiftUI binding errors?

Yes, it provides specific fixes for $viewModel property errors by implementing the correct @Bindable wrappers in your Views.

How does this skill help with Swift 6 migrations?

It provides specific implementation patterns for @MainActor isolation and nonisolated functions to ensure code complies with the latest concurrency requirements.
