Does it support both UIKit and SwiftUI?

Yes, while it includes specific guidance for SwiftUI architecture, the debugging loop and simulator tools work for any iOS application regardless of the UI framework used.

Can I use this for UI testing?

Yes. The skill includes tools for simulator interaction such as tapping, swiping, and entering text, making it highly effective for reproducing bugs and verifying UI behavior.

How does the Debug skill interact with my iOS project?

The skill uses the XcodeBuildMCP and ios-simulator tools to build your project, launch the app in a simulator, and capture diagnostic data like screenshots and logs directly within the Claude environment.

Will Claude change my code without asking?

No. This skill follows a strict 'Confirm before implementing' policy, requiring explicit user approval via the AskUserQuestion tool before any code modifications are made.

Mobile Development

Diagnoses and resolves iOS application issues through a structured loop of simulator interaction, log analysis, and visual verification.

The Debug skill transforms Claude into a specialized QA and debugging engineer for iOS development. By leveraging XcodeBuildMCP and ios-simulator tools, it allows Claude to capture the app's visual state via screenshots, analyze real-time runtime logs, and identify the root cause of functional or layout errors. The skill enforces a rigorous feedback loop—gathering diagnostics, proposing specific fixes, obtaining user confirmation, and verifying results with side-by-side comparisons—ensuring that app behavior aligns perfectly with developer expectations.
