## Topics Covered

### 1. EAS Build Setup
```bash
# Install EAS CLI
npm install -g eas-cli

# Login
eas login

# Configure
eas build:configure

# Build
eas build --platform all --profile production
```

### 2. EAS Configuration
```json
// eas.json
{
  "build": {
    "development": {
      "developmentClient": true,
      "distribution": "internal"
    },
    "production": {
      "autoIncrement": true
    }
  },
  "submit": {
    "production": {
      "ios": { "appleId": "your@email.com" },
      "android": { "track": "production" }
    }
  }
}
```

### 3. iOS Code Signing
```bash
# With Fastlane Match
fastlane match appstore

# Manual (Xcode)
# 1. Create certificate in Apple Developer
# 2. Create provisioning profile
# 3. Download and install in Xcode
```

### 4. Android Keystore
```bash
# Generate keystore
keytool -genkeypair -v -storetype PKCS12 \
  -keystore release.keystore \
  -alias my-key-alias \
  -keyalg RSA -keysize 2048 -validity 10000

# NEVER commit keystore or passwords
```

### 5. OTA Updates
```typescript
// Check for updates
import * as Updates from 'expo-updates';

async function checkUpdates() {
  const update = await Updates.checkForUpdateAsync();
  if (update.isAvailable) {
    await Updates.fetchUpdateAsync();
    await Updates.reloadAsync();
  }
}
```

### 6. Submission Commands
```bash
# Build and submit in one command
eas build --platform all --profile production --auto-
