Bitrig is an AI-powered development tool for building native Swift and SwiftUI applications for Apple platforms. Users describe the app they want in plain English, and Bitrig generates real, editable Swift code that can be reviewed, modified, and shipped to the App Store. It supports a conversational workflow where users request code changes naturally, with updates reflected immediately. An integrated iPhone simulator lets developers preview their apps alongside the code in real time. Designed for macOS on Apple silicon, Bitrig helps developers create, test, refine, and learn Swift applications within a single environment.
