ios-builder: iOS Development Without a Mac via Cloud CI and MobAI

RepositoryMobAI-App/ios-builderTool

ios-builder is an open-source CLI tool that lets developers build and test iOS applications from Windows or Linux. It relies on GitHub Actions, Codemagic, or Bitrise for remote builds and connects to MobAI for simulator streaming and hot reload.

Key points

  1. Mac-free workflow: Build and test iOS apps directly from Windows, Linux, or any other platform.
  2. CI provider support: Uses macOS runners on GitHub Actions (default), Codemagic, or Bitrise, with separate authentication per provider.
  3. Working-tree snapshots: builder ios build syncs uncommitted and untracked local changes to a temporary hidden Git ref without creating commits on branches.
  4. Simulator and device tooling: Enables remote iOS simulator access and hot reload for Flutter and React Native on real devices via MobAI.
  5. Distribution and signing: Supports code signing, over-the-air installation via QR code, and uploads to TestFlight or App Store via App Store Connect API.

Why it matters

iOS development traditionally requires local macOS hardware. ios-builder offloads compilation to cloud CI infrastructure and brings interactive simulator testing to non-Mac environments, reducing hardware lock-in.

Analysis

Written in Go, ios-builder tackles a persistent pain point for cross-platform developers. Instead of forcing manual commits for remote testing, its snapshot mechanism pushes transient working-tree state to ephemeral hidden refs. Integration with MobAI 3.0 provides remote simulator interaction, which can also be operated by coding agents like Claude Code, Codex, or Cursor. With over 1,100 GitHub stars, an MIT licence, and full pipeline coverage up to App Store submission, it offers a mature solution for non-Mac environments.
