Xcode
Xcode is Apple's main tool for creating apps for iPhones, iPads, and Mac computers. It's like a complete workshop where developers build, test, and polish apps before they appear on the App Store. Think of it as the equivalent of Microsoft Word for app developers – it's the standard program they use to write code, design the app's appearance, and make sure everything works correctly. When you see Xcode mentioned in a resume, it typically means the person has experience in creating Apple-specific applications.
