Xcode
Overview
What Xcode is
Xcode is the all-in-one development environment Apple provides for creating software for its platforms. It supports Swift and Objective-C (and C/C++), and includes the SDKs, compilers, and frameworks required to target iPhone, iPad, Mac, Apple Watch, and Apple TV.
It is distributed free through the Mac App Store and runs only on macOS. That macOS requirement is a core constraint: building and signing native Apple apps ultimately requires a Mac running Xcode, even when the app itself is written in a cross-platform framework.
What Xcode includes
Beyond the code editor, Xcode ships with Interface Builder for designing UI, a built-in Simulator to run apps on virtual iPhones and iPads, and Instruments for performance profiling and memory analysis. It integrates source control, unit and UI testing, and the build system that compiles and packages your app.
It also handles code signing, provisioning profiles, and submission to App Store Connect and TestFlight for beta distribution. SwiftUI previews let developers see interface changes live as they edit code.
Why Xcode matters
Any team shipping to the Apple App Store depends on Xcode at some stage—for the final native build, signing, and submission—even if development happens in React Native or Flutter, which still compile through Xcode for iOS.
Because it is free and comprehensive, Xcode lowers the barrier to native Apple development, but the Mac-only requirement is a real planning factor for teams that otherwise work on Windows or Linux.

FAQ
Xcode — common questions
Is Xcode free?
Yes. Xcode is available at no cost from the Mac App Store. You only need a paid Apple Developer Program membership when you want to distribute apps on the App Store or test on physical devices beyond the free provisioning limits.
Can I run Xcode on Windows?
No. Xcode runs only on macOS. Building and signing native iOS apps requires a Mac, which is why cross-platform teams often use a Mac (or a cloud Mac service) for the final iOS build and submission steps.
Do I need Xcode for React Native or Flutter iOS apps?
Yes. Even when you write an app in React Native or Flutter, the iOS version is compiled, signed, and submitted through Xcode on a Mac. Xcode also provides the iOS Simulator used during development.
