Bitrig, created by ex-Apple SwiftUI engineers, launches Mac app that generates Swift code and builds iPhone apps through prompts, complete with Xcode toolchain and simulator.
Built by a group of ex-Apple employees who co-created SwiftUI, Bitrig now lets you build iPhone apps right from your Mac through prompts. Here are the details.
From iPhone to Mac: Bitrig expands its AI coding platform
Bitrig, the AI-powered coding platform that launched on iOS last October, has released a Mac version that brings iPhone app development to the desktop. The company, founded by former Apple engineers who helped create SwiftUI, says the Mac app was one of the most requested features since the iOS launch.
How Bitrig works for iPhone development
The platform generates actual Swift and SwiftUI code that users can build and deploy. According to Bitrig, developers can ship their apps to TestFlight or even the App Store if they choose. The Mac version offers several advantages over the iOS version:
- Full keyboard input for faster coding
- Access to the complete Xcode toolchain
- Support for every framework in the iOS SDK
- Larger screen real estate for development work
Key features for Mac developers
The Mac app includes several tools designed to streamline the development process:
Image and screenshot uploads - Users can upload visual assets directly into their projects
Integrated iPhone simulator - Preview and interact with apps without needing a physical device
One-click device deployment - Send apps to connected iPhones for on-device testing
Code editing capabilities - Users can read and edit generated code by hand, helping them learn Swift syntax and structure
Xcode project export - Export code as standalone Xcode projects for further development
Pricing and credits system
Bitrig operates on a message credit system:
- Free accounts: 5 daily credits (up to 30 per month)
- Plus accounts: 200-1,600 monthly credits depending on tier
- Credits shared between Mac and iOS versions
- Unused credits roll over to the next month with active subscription
- Projects sync across iOS and macOS versions
System requirements
The Mac app requires macOS Sequoia 15 or later, ensuring compatibility with the latest Apple development tools and frameworks.
The bigger picture: AI-assisted development grows
Bitrig represents a growing trend in AI-assisted software development, particularly for mobile platforms. By combining natural language prompts with actual code generation, the platform aims to lower the barrier to entry for iPhone app development while still producing production-ready code.
The involvement of SwiftUI's creators suggests deep integration with Apple's development ecosystem, potentially offering more sophisticated code generation than general-purpose AI coding tools.
For developers interested in exploring Bitrig, the platform is available through the Mac App Store, with the iOS version continuing to serve mobile users who want to code on the go.
