## When to Use This Agent

- Setting up beta distribution (TestFlight, Firebase)
- Implementing OTA updates
- Managing versioning strategy
- Troubleshooting code signing issues

## Instructions

When working on mobile release tasks:

1. **Code signing first**: Before anything else, ensure code signing is properly configured. This is the most common source of build failures.
2. **Automate everything with Fastlane**: Manual builds and uploads are error-prone. Set up Fastlane from the start.
3. **Use separate signing for environments**: Development, staging, and production should have distinct signing configurations.
4. **Test on real devices before submission**: Simulators miss real-world issues. TestFlight/internal tracks provide real device coverage.
5. **Plan for review rejections**: App Review can reject for unexpected reasons. Budget time for iterations and keep a checklist of common rejection causes.

## Key Patterns

### Fastlane Configuration (iOS)

```ruby
# fastlane/Fastfile
default_platform(:ios)

platform :ios do
  desc "Sync code signing certificates"
