How We Build iOS Apps Without Making You Buy a Mac
Here's a frustrating reality of iOS development: you can write your app on Windows, design it on Figma, test it in a simulator—but the moment you want to actually compile it into an installable IPA, you need a Mac running Xcode.
Apple has made this non-negotiable. The code signing process requires macOS-specific toolchains that can't be legally replicated on other operating systems.
So we built a fleet of Mac Mini workers that do the compilation for you.
The build pipeline architecture
When you click "Build" in our dashboard, here's what happens:
The hard part: certificate management
Building the Swift code is actually the easy part. The hard part is code signing.
Every iOS app must be signed with a valid Apple certificate and provisioning profile. If you've ever dealt with "Signing for 'App' requires a development team" errors in Xcode, you know the pain.
We use Fastlane Match to handle this complexity. When you upload your certificates to our platform, here's what happens:
Ephemeral keychains
We create a temporary macOS keychain just for your build. Your certificate is imported, used for signing, then the keychain is destroyed. No persistence.
Encrypted storage
Your P12 files are encrypted at rest using AES-256. They're only decrypted on the worker during active builds, then purged from memory.
The hardware: Apple Silicon workers
Speed matters. Our workers run on M-series Mac Minis (currently M2 and M2 Pro configurations).
This isn't just about being "fast"—Apple Silicon reduced our average iOS build time from ~12 minutes (Intel) to ~3-5 minutes. That's the difference between waiting for a build and getting your app while your coffee is still hot.
On trusting us with your certificates
Yes, you're uploading your Apple signing certificates to a third party. We take this seriously—we're a small team with our reputations on the line. But if your security policy prohibits third-party certificate access, you'll need to build locally using our source code export option.
How is this different from Expo EAS?
Expo EAS is excellent if you're building a React Native app from source code.
But Code2Native solves a different problem: you already have a website, and you want to wrap it in a native container. You don't have React Native code. We provide the Swift/Kotlin template; you just configure it.
Think of us as "EAS for websites"—same cloud build concept, different input.
