Xcode is Apple's official, free IDE for building software for iPhone, iPad, Mac, Apple Watch, and Apple TV. It ranks #13 in real-world usage at about 10% share — essentially every Apple-platform developer uses it, since it's the only IDE Apple allows for submitting apps to the App Store.
📌 Quick facts

License: Free (Mac App Store)

Getting started
Install it from the Mac App Store, or grab just the command-line tools:
# Just the command-line tools
xcode-select --install
Open the Mac App Store, search "Xcode," install, then create a New Project and pick a template (App, Framework, Game, etc.).
🎯 Best for: Anyone building an app that will ship on an Apple device or to the App Store — there's no real alternative, since Apple requires Xcode for submission.
