Quick Setup Commands

iOS (macOS)

# Install Xcode command line tools
xcode-select --install

# Accept Xcode license
sudo xcodebuild -license accept

# Install CocoaPods
sudo gem install cocoapods

# Install watchman
brew install watchman

# Verify setup
xcodebuild -version
pod --version
watchman version

Android (All Platforms)

# Verify Android setup
echo $ANDROID_HOME
adb --version
emulator -version

# List available emulators
emulator -list-avds

# List connected devices
adb devices

React Native Project

# Create new React Native project
npx react-native init MyProject

# Navigate to project
cd MyProject

# Install iOS dependencies
cd ios && pod install && cd ..

# Start Metro bundler
npm start

# Run on iOS (separate terminal)
npm run ios

# Run on Android (separate terminal)
npm run android

Pro Tips

  1. Clean Builds: When in doubt, clean everything

    # iOS
cd ios && rm -rf build Pods && pod install && cd ..

# Android
cd android && ./gradlew clean && cd ..

# Metro
npx react-native start --reset-cache

  2. Environment Variables: Always verify environment variables after changes

    # Add to ~/.zshrc or ~/.bash_profile
export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/platform-tools

# Reload shell
source ~/.zshrc

  3. Simulator Management: List and boot specific devices

    # iOS
xcrun simctl list devices
xcrun simctl boot "iPhone 15 Pro"

# Android
emulator -list-avds
emulator -avd Pixel_6_API_34

  4. Quick Health Check: Verify entire environment

    node --version      # Node.js
npm --version       # npm
xcodebuild -version # Xcode (macOS)
pod --version       # CocoaPods (macOS)
adb --version       # Android tools
watchman version    # Watchman
