Bitrig

Bitrig is an AI development environment for building native Swift apps across Apple platforms: describe the app in natural language and it generates real Swift code and full Xcode projects, driven by agents built on Claude Code and Codex. Built into the workflow are a simulator, automated tests, code editing, GitHub integration, backend support via CloudKit or Supabase, and — critically for Apple's ecosystem — the path to actually shipping to the App Store.

The credibility line matters in this category: the team includes co-creators of SwiftUI. Compared with generic "AI app builders" that produce web wrappers, Bitrig's native Swift output is a genuinely different product.

Who it's for: indie developers and founders targeting iOS who want the idea-to-App-Store path compressed, and designers who'd rather prototype in something that produces real code. It's a Mac download, so plan accordingly. As with all AI app generators, review the generated Swift before shipping anything that touches user data — the compiler passing isn't the same as the architecture being right.
