feat(ios): add comprehensive requirements checking and improved CocoaPods detection
Enhanced iOS test app setup with better prerequisite handling:
Requirements Checker:
- Created check-requirements.sh script
- Verifies all prerequisites (macOS, Xcode, Ruby, CocoaPods, Node.js)
- Checks Ruby version (requires 3.1+)
- Detects CocoaPods in multiple locations (PATH, rbenv, gem bin)
- Validates UTF-8 encoding
- Provides installation instructions for missing items
Build Script Improvements:
- Enhanced CocoaPods detection (checks PATH, rbenv, gem bin)
- Better error messages with installation options
- Automatic LANG=en_US.UTF-8 export
- Uses detected pod command location
Documentation Updates:
- Expanded prerequisites section with versions
- Added rbenv recommendation
- Added quick requirements check step
- Clearer installation instructions
Fixes:
- Handles rbenv-based CocoaPods installation
- Works with system Ruby, rbenv, or Homebrew
- Provides helpful error messages
Result: Developers can easily verify and install all requirements
