Xcode Overview
Xcode is Apple's integrated development environment for building apps across all of Apple's platforms, including iPhone, iPad, Mac, Apple Watch, and Apple TV, and it runs on macOS. It bundles everything needed to create, test, and ship software for the Apple ecosystem: a code editor with completion and refactoring for Swift and Objective-C, Interface Builder for designing user interfaces visually, simulators for running apps without physical devices, and a debugger and performance instruments for finding and fixing issues. Xcode integrates the iOS, macOS, watchOS, and tvOS SDKs, manages app signing and provisioning, and connects directly to App Store Connect for submitting apps to the App Store. It also includes source-control integration, automated testing tools, and live previews for SwiftUI. Xcode is free from Apple and is distributed through the Mac App Store and Apple's developer site.
