Can I build iOS apps without a Mac?

Yes. ios-builder is MobAI's open source CLI that builds your Xcode project on a remote Mac runner and hands you back the app. You run it from Linux, Windows, or a cloud sandbox.

Can I test on a real iPhone from Linux?

Yes. After a one-time guided setup, your iPhone joins your private tailnet and stands on its own: no cable, no host machine. MobAI reaches it from Linux, Windows, and cloud sandboxes, and your agent sees the screen and taps it like a local device.

Do I need to own a Mac at all?

No. There are Macs in the loop for builds and simulators, but they are remote runners. You never need one on your desk.

Can my AI agent preview SwiftUI without Xcode?

React Native and Flutter previews run in cloud sandboxes today. SwiftUI previews rendered straight from Swift source are in development.

iOS development
without a Mac.

Build, run, and test real iOS apps from Linux, Windows, or a cloud sandbox. There are Macs in the loop. They're remote, and they're not yours.

Get MobAI ios-builder on GitHub

Works from Linux, Windows, and the sandboxes where coding agents live.

01 · iOS builds

Build the app anywhere

ios-builder takes your Xcode project, builds it on a remote Mac runner, and hands the app back. One CLI call from any machine. It's open source.

Your agent edits Swift in its sandbox, kicks a build, and installs the result on a device or simulator without ever leaving Linux.

$ ios-builder build ./MyApp.xcodeproj
→ remote runner: Xcode 16, arm64
→ MyApp.ipa ready in 4m 12s

$ mobai install MyApp.ipa --device iphone

02 · Real iPhones

Your iPhone, reachable from anywhere

Your iPhone joins your private tailnet and stands on its own. No cable, no host machine, no relay in the middle, no shared farm hardware. Reach it from Linux, Windows, or a cloud sandbox.

Setup is a one-time step: MobAI walks you through it with the phone plugged into any computer you have. Mac, Linux, or Windows. After that the phone just needs power and a network.

$ mobai devices
iphone-15-pro   ios 18.2   tailnet · home
pixel-8         android 15 usb · local

$ mobai screenshot iphone-15-pro

03 · Remote simulators

Simulators on demand

Real Apple simulators booted on GitHub-hosted runners when you need them. Your agent drives them exactly like a local device: same commands, same protocol.

Spin one up for a test run, throw it away after. Nothing to maintain.

$ mobai simulator up --model iphone-16-pro
→ booting on gh runner… ready

$ mobai test flows/ --device sim-remote

04 · App previews

See the screen inside the sandbox

Preview app screens right where the agent works. No simulator boot, no build round-trip: the engine renders true iPhone frames the agent can look at and iterate on.

React Native and Flutter today. SwiftUI, rendered straight from Swift source, is in development.

$ mobai-dev preview ./lib/settings.dart
→ engine: flutter · iphone frame · light
→ preview.png  (agent reads the pixels)

05 · App Store

From sandbox to TestFlight

Signing, uploading, and TestFlight handling from the same pipeline, so an agent can take a change from code to testers without you touching Xcode. In the works.
