Kyle Macomber is an American software engineer and entrepreneur who is the co-founder and chief executive officer of Bitrig, a macOS application that uses artificial intelligence to generate native Swift and SwiftUI code for iOS apps from natural language descriptions.[1] Prior to founding Bitrig, Macomber spent approximately fourteen years at Apple Inc., where he was a founding member of the SwiftUI framework team and later managed the Swift Standard Library team.
Career
Apple
Macomber worked at Apple for over a decade in roles focused on core frameworks and developer tools. He was a founding member of the team that created SwiftUI, Apple's declarative user interface framework for building applications across its platforms. He subsequently managed the Swift Standard Library team, where he contributed to the delivery of Swift Concurrency, first-class support for regular expressions, and the launch of widely used open-source packages including Swift Algorithms, ArgumentParser, and Collections.[2]
Bitrig
Macomber co-founded Bitrig, a tool designed to allow users — including those with no prior coding experience — to build and ship native iPhone applications to the App Store. The application runs on macOS (Sequoia 15 or later) and operates through a conversational workflow: users describe what they want to build or change in plain English, and Bitrig generates corresponding Swift and SwiftUI code. The tool includes an integrated iPhone simulator that displays a real-time preview of the app alongside the generated source code, allowing users to see exactly what the final product will look like.[3]
Bitrig was part of Y Combinator's Summer 2025 batch. In September 2025, Business Insider named Bitrig among the most notable AI-powered "vibe coding" tools emerging from that cohort of startups.[4]
The product has attracted users with varying levels of technical ability. User testimonials on the Bitrig website include accounts from individuals with no prior programming experience, as well as a blind user who described the tool as making app development newly accessible.[5]
Personal life
Macomber is based in Los Altos, California.[6]
