Xcode

Xcode is Apple's integrated development environment (IDE) for developing applications and other software for macOS. It was introduced in 2003 for Mac OS X running on PowerPC, and then Intel processors.

On June 22 at the 2020 Worldwide Developers Conference, a developer beta of Xcode 12 was introduced with support for Universal 2 binaries that can run on 64-bit Intel and Apple processors.

Features
Xcode extends and replaces Apple's previous development tools: Project Builder (inherited from NeXT) and Macintosh Programmer's Workshop (for classic Mac OS software). It also superseded CodeWarrior, a popular 3rd-party IDE for developing classic and Carbonized PowerPC software.

Xcode works hand in hand with Interface Builder (also inherited from NeXT), a graphical tool used to create user interfaces.

Xcode includes GCC, and can compile C, C++, Objective C++, Java, and Objective C source code with a variety of programming models, including but not limited to Cocoa, Carbon, and Java.).

Release history
Xcode was first included free with Mac OS X 10.3, which shipped in October 2003. It is able to develop OS X applications that can run on any version of OS X. However, it did not officially work in Mac OS X 10.2. Xcode has been available from the App Store since version 4.
