Debug - iOS App Debugging Loop

Use XcodeBuildMCP and ios-simulator MCPs to diagnose issues, capture app state, and collaborate with users on fixes. Always confirm before making changes.

Workflow

1. Capture current state — Use ios-simulator to capture screenshots and understand the current visual state of the app. Use XcodeBuildMCP to read build logs and runtime errors.

2. Gather diagnostic information — Collect relevant information:

   • Screenshot of the issue using ios-simulator
   • Console logs and error messages from XcodeBuildMCP
   • App state and behavior observations
   • Ask: "Looking at this screenshot and these logs, can you describe exactly what's wrong or what you expected to happen?"

3. Analyze the problem — Review the captured information:
