How does this skill help with SwiftUI view updates?

It provides a step-by-step decision tree to identify if the issue stems from direct struct mutation, lost binding identity, accidental view recreation, or missing observer patterns.

Can it help fix Xcode Preview crashes?

Yes, it includes diagnostics to distinguish between code errors, missing environment objects, and Xcode cache corruption that causes previews to fail.

What is Self._printChanges() and how is it used?

It is a powerful diagnostic tool included in the skill that reveals exactly which property triggered a view redraw, helping you eliminate unnecessary renders.

Does it support the latest iOS 17 state management?

Absolutely. It contains specific patterns and debugging steps for the @Observable macro, @Bindable, and how they differ from older ObservableObject patterns.

Identifies and resolves SwiftUI view update failures, preview crashes, and layout issues using systematic diagnostic decision trees.

概要

The axiom-swiftui-debugging skill provides a structured framework for troubleshooting complex SwiftUI issues, moving beyond guesswork to systematic diagnostics. It offers detailed decision trees for common failure modes like lost binding identity, accidental view recreation, and missing observer patterns. With support for modern iOS 17+ features like @Observable and native debugging tools like Self._printChanges(), this skill helps developers quickly isolate root causes in UI state, previews, and layouts to maintain high-performance xOS applications.
