iOS Testing Automation FAQs

Question 1

What is the difference between expo-mcp and xc-mcp in this skill?

expo-mcp handles React Native-specific actions like finding elements by testID and capturing screenshots within the app, while xc-mcp manages the iOS simulator environment, including booting devices, installing .app bundles, and launching processes.

Question 2

Does this skill require specific code changes in my app?
