Simulator Utilities

Quick reference for iOS Simulator commands. Use these patterns whenever working with simulators.

Screenshot with Auto-Resize (REQUIRED)

ALWAYS use this pattern when taking screenshots to avoid API errors:

# Single command: screenshot + resize
xcrun simctl io booted screenshot /path/to/screenshot.png && sips --resampleHeightWidthMax 1800 /path/to/screenshot.png

Why Resize?

• iPhone 17 simulator screenshots exceed 2000px
• Claude API rejects images >2000px in multi-image requests
• sips --resampleHeightWidthMax 1800 keeps images under limit
