Deploying an iOS app is a multi-step journey that moves from your local machine to Apple's cloud. As an Architect, you must manage three distinct environments: Development (for active coding), Staging/TestFlight (for stakeholder feedback), and Production (the public App Store). Each step requires a specific set of cryptographic 'Certificates' and 'Profiles' to verify the app's authenticity.

This is often the most complex part of native development. Code signing ensures that the code has not been altered since you signed it. You need two components:

Before going public, you should use TestFlight. It allows you to distribute 'Beta' builds to up to 10,000 external testers using just their email. For your Revochamp team, this is the phase where you catch native crashes that didn't appear in the simulator.

Once a build is uploaded via Xcode, you manage its metadata (screenshots, descriptions, and pricing) in App Store Connect. Every update is manually reviewed by Apple employees. As a Lead, you must ensure the app complies with Guideline 2.1 (Performance) and Guideline 5 (Privacy) to avoid delays.

For a Technical Lead, manual archiving in Xcode is inefficient. You should implement Fastlane to automate the generation of screenshots, management of provisioning profiles, and the uploading of builds to TestFlight directly from your CI pipeline (GitHub Actions or GitLab CI).
