Bitrig

What It Does

Bitrig is an AI-powered development environment for macOS that transforms natural language descriptions into complete, production-ready native Swift applications. Built by co-creators of SwiftUI, Bitrig generates real Xcode projects with the full Apple toolchain and latest SDKs, enabling developers and creators to build and ship iOS, iPadOS, watchOS, tvOS, and visionOS apps directly to the App Store.

Key Features & Capabilities

• AI-Powered Code Generation: Uses frontier AI models from Anthropic (Claude) and OpenAI to generate Swift code from natural language prompts
• Built-In Testing & Debugging: Automatically tests apps by simulating user interactions (tapping, scrolling, typing) and fixes bugs it discovers
• Photorealistic 3D Simulators: Preview apps in interactive 3D device frames with rotation and dynamic lighting
• Complete App Store Workflow: Archive builds, upload to TestFlight, manage App Store listings, capture localized screenshots, and handle code signing—all within Bitrig
• Advanced Apple Platform Features: Build widgets, Live Activities, controls, App Intents, Shortcuts integration, Siri support, and Watch complications
• Backend Integration: Native support for CloudKit and Supabase for secure data sync across devices
• Monetization Tools: Add in-app purchases, subscriptions, native paywalls with StoreKit, and RevenueCat integration via prompts
• GitHub Integration: Contribute changes through standard GitHub workflows your team already uses
• Bring Your Own Subscription: Connect existing Claude or ChatGPT subscriptions instead of paying per-token API prices

Who It's For

Bitrig serves indie developers, app creators, startups, and teams who want to accelerate Swift app development without sacrificing code quality or control. It's ideal for those who want to leverage AI assistance while maintaining full access to real Xcode projects and native Apple development workflows.

What Makes It Different

Unlike web-based code generators, Bitrig produces genuine Xcode projects that can be opened and edited in Xcode anytime. It handles the entire app lifecycle from initial code generation through App Store submission, including complex tasks like screenshot automation and in-app purchase configuration. The companion Bitrig Remote app even enables building and shipping apps from iPhone or iPad by connecting to Bitrig on Mac.
