Xcode
Apple's free IDE for building apps across iOS, macOS, watchOS, and tvOS with Swift or Objective-C.
What is Xcode?
Xcode is Apple's integrated development environment for building apps across all Apple platforms.
It bundles everything you need: code editor with predictive completion, visual interface builder, iOS simulator, debugging tools, and TestFlight integration for beta testing.
Most iOS developers use it daily to write Swift code, preview UI changes in real-time, test on simulated devices, and submit apps to the App Store. The latest version (Xcode 16) includes AI-powered code completion and agentic coding features powered by on-device models.
Free to download from the Mac App Store. Requires a Mac running macOS. You'll need an Apple Developer account ($99/year) to publish apps to the App Store.
