Build an iPhone App
Without a Mac
Xcode only runs on macOS — that part is true and is not changing. What is no longer true is that you need one: the build, the signing and the App Store submission all happen in the cloud. Describe your app, get React Native code, download a signed IPA from Windows, Linux or a Chromebook.
Can you build and publish an iPhone app without owning a Mac?
Yes, and most guides on this question are out of date. They tell you that writing and testing can happen on Windows but that **the final build, code signing and App Store submission still require a Mac running Xcode**. That was true for years and is no longer true: the build and the signing happen on the service's side, and you get back an installable IPA. You still need an Apple Developer account at $99/year — nobody can remove that — but you do not need the machine, the licence or Xcode. Fastshot generates the React Native project and runs that build for you; Expo's EAS Build does the same if you already have a codebase.

What is an Online iOS Builder?
An online iOS builder is a platform that allows you to create, compile, and package iOS applications without owning a Mac or installing Xcode locally. The development environment and build infrastructure run entirely in the cloud, accessible through a web browser.
Apple ecosystem has traditionally required expensive hardware to participate in. Xcode runs only on macOS, which means a Mac is normally a non-negotiable requirement for iOS development. This hardware barrier has locked out many potential app creators worldwide.
Fastshot breaks through this limitation by pairing AI-powered code generation with cloud-based iOS builds. Describe your app in natural language from any computer, and Fastshot generates a React Native + Expo project. Cloud build servers running macOS compile the project into a signed IPA file.
The result is democratized iOS development. A Windows user, a Chromebook owner, or someone on a Linux workstation can build, test, and ship iOS apps without ever touching a Mac. Combined with full source code ownership, this makes Fastshot the most accessible path to the App Store available today.
How Online iOS Building Works
Open Fastshot in Any Browser
Access the platform from Windows, Linux, ChromeOS, or any other system. No Mac hardware or macOS software needed.
Describe Your iOS App
Explain the app you want to build. Fastshot AI generates a complete React Native + Expo project with iOS-optimized components and patterns.
Preview on iPhone
Use Expo Go on your iPhone to see the app running in real time. Test gestures, navigation, and every screen before building.
Cloud Build Produces IPA
Cloud servers running macOS compile and sign your IPA file. Download it for TestFlight upload or direct App Store submission.
Online iOS Builder Features
No Mac Hardware Needed
Cloud build servers handle Xcode compilation. Build iOS apps from Windows, Linux, ChromeOS, or any platform with a browser.
Cloud Code Signing
Provide your Apple Developer credentials and the cloud handles provisioning profiles, certificates, and code signing automatically.
TestFlight Integration
Upload the generated IPA directly to TestFlight for beta testing with up to 10,000 external testers before your public launch.
iOS-Optimized Output
Generated code follows Apple Human Interface Guidelines with proper safe areas, typography scales, and navigation patterns.
Real-Time iPhone Preview
See your app on a real iPhone as you iterate. Make changes via chat and watch the preview update instantly on your device.
Same Project, Android Too
The generated React Native + Expo project targets both platforms. Build for Android from the same codebase whenever you are ready.

Online iOS Builder FAQ
Yes. Compiling an iOS app requires Xcode, and Xcode only runs on macOS — but that Mac does not have to be yours. Fastshot compiles your app on cloud macOS build servers: you work in a browser on Windows, Linux or ChromeOS and receive a signed IPA for TestFlight and the App Store. You need a browser and an Apple Developer account, nothing else.
Only for the compile step, and the compile step can run on someone else's Mac. Fastshot's cloud build servers run macOS and Xcode; your machine never touches them. What you cannot avoid is Apple's Developer account ($99/year) for TestFlight and App Store distribution — that requirement is Apple's, not the tooling's.
Yes, three ways that work. Cloud builds — Fastshot, EAS or Codemagic — compile your code on a remote Mac, so you only need a browser. Renting a cloud Mac such as MacinCloud gives you real Xcode, billed hourly, and you still have to learn it. A macOS virtual machine on a PC violates Apple's license and breaks with every update.
Xcode does the compiling, but it can live on the build server instead of your machine. In Fastshot, Xcode runs in the cloud and you never open it. You also do not need Swift or SwiftUI: the generated code is React Native, which compiles into a native iOS app that Apple reviews the same way as a Swift one.
Yes. Describe the app in Fastshot, and the AI generates the React Native code. Install Expo Go on your iPhone and scan the QR code to run it on the device. Refine in chat, then trigger a cloud IPA build and submit it to TestFlight or the App Store. No Mac, no Xcode, no Swift.
Building and testing, yes: describing the app in Fastshot and running it on your iPhone through Expo Go costs nothing. Publishing is where the fixed costs live — Apple's $99/year Developer account, plus Fastshot's cloud iOS builds, which are in paid plans. Without the Apple account you can still test in Expo Go and the simulator, just not distribute.
Yes. To distribute apps on the App Store or TestFlight you need an Apple Developer account ($99/year), and that is true for every tool, Fastshot included. Fastshot handles the build and signing; Apple requires the account for distribution. It can be created from any computer or from the iPhone itself.
Yes, at two stages. During development, install Expo Go from the App Store and scan the QR code Fastshot shows to run the app on your iPhone in real time. For beta testing, TestFlight lets up to 10,000 testers install the build from a link, with no computer or cable involved. Test keyboard, safe areas and notifications on a real device before submitting.
Rent a Mac if your goal is to learn Swift and Xcode — you get the standard environment, billed hourly. Use a cloud build service if your goal is to ship an app: no hourly meter, no laggy remote desktop, no Xcode to learn. Fastshot's builds run in minutes and go straight to TestFlight; Codemagic and Xcode Cloud do the same for projects you already have code for.
Yes. Fastshot generates React Native code that renders through native iOS components — native navigation, animations and platform styling, not a website in a shell. Through Expo you get camera, push notifications, biometrics, haptics, maps, in-app purchases, Apple Sign-In and more. Adding Swift modules is possible but the primary workflow is the cross-platform code.
