It contains code programs can use to create and interact with graphical user interfaces. AppKit is built on top of Foundation, and uses the same NS prefix. Core Data is the object persistence framework included with Foundation and Cocoa and found in Cocoa.h. [1] A key part of the Cocoa architecture is its comprehensive views model.
In Xcode 3.2 and later, it included the Clang C/C++/Objective-C compiler, with newly-written front ends and a code generator based on LLVM, and the Clang static analyzer. [14] Starting with Xcode 4.2, the Clang compiler became the default compiler, [ 15 ] Starting with Xcode 5.0, Clang was the only compiler provided.
The following is an example of a simple Hello World program. The @main attribute defines the entry point into the app. It is standard practice in SwiftUI to separate the application struct and views into different structs, according to the Model–View–ViewModel (MVVM) architectural pattern.

Export to Xcode; One notable feature is 'Export to Xcode'. A sample Xcode project is created with C source code to initialize OpenGL (using the GLUT library) and run the shader program. Note that this program is no longer recommended for editing GLSL shaders as "GLSLEditorSample," available as an example program, is generally regarded as superior.
Apple's Xcode 2.1 supports the creation of these files, a new feature in that release. A simple application developed with processor-independence in mind might require very few changes to compile as a universal binary, but a complex application designed to take advantage of architecture-specific features might require substantial modification ...
Xcode has built-in functionality for developing a Cocoa application using AppKit, including the ability to visually design user interfaces with Interface Builder. It relies heavily on patterns like reference types, delegation, notifications, target–action, and model–view–controller. A sign of the NeXTSTEP heritage, AppKit's classes and ...

ATSUI was replaced by a faster [1] and modern Unicode imaging engine called Core Text in Mac OS X 10.5 (Leopard).. It was officially deprecated with Xcode 4.6, which was released in December 2012: "Source code using ATS APIs will generate warnings while being compiled.
