App Store Deployment

When to use

• Configuring App Store Connect or Google Play Console for a new app
• Setting up TestFlight or Play testing tracks for beta distribution
• Implementing Fastlane lanes for automated builds and submissions
• Debugging code signing, provisioning profiles, or keystore issues
• Preparing a submission and ensuring review guideline compliance
• Rolling out a release with phased/staged rollout controls
• Integrating Crashlytics or Sentry for symbolicated crash reporting

Core principles

1. Automate signing — manual certificate juggling in CI is how you lose a signing key at 2 AM
2. Fastlane match — Git-encrypted certificates; the whole team uses one source of truth
3. Two pins minimum — primary + backup certificate pin; never ship pinning that can lock users out
4. Phased rollout always — 1% first; monitor crash rate before widening; pausing beats rolling back
5. dSYM/mapping upload is not optional — unreadable stack traces in production are unacceptable
