The name "Grand Central Dispatch" is a reference to Grand Central Terminal. [citation needed] The source code for the library that provides the implementation of GCD's services, libdispatch, was released by Apple under the Apache License on September 10, 2009. [3] It has been ported [4] to FreeBSD 8.1+, [5] MidnightBSD 0.3+, [6] Linux, and Solaris.
Apple designed blocks with the explicit goal of making it easier to write programs for the Grand Central Dispatch threading architecture, [3] [4] although it is independent of that architecture and can be used in much the same way as closures in other languages.
The Swift Programming Language, a free 500-page manual, was also released at WWDC, and is available on the Apple Books Store and the official website. [28] Swift reached the 1.0 milestone on September 9, 2014, with the Gold Master of Xcode 6.0 for iOS. [29] Swift 1.1 was released on October 22, 2014, alongside the launch of Xcode 6.1. [30]

Swift [1] is an implicitly parallel programming language that allows writing scripts that distribute program execution across distributed computing resources, [2] including clusters, clouds, grids, and supercomputers. Swift implementations are open-source software under the Apache License, version 2.0.
In computer science, message passing is a technique for invoking behavior (i.e., running a program) on a computer.The invoking program sends a message to a process (which may be an actor or object) and relies on that process and its supporting infrastructure to then select and run some appropriate code.

Apple is also releasing APIs for Grand Central Dispatch for developers to use in their applications and also to analyze specific blocks of code running on Grand Central Dispatch. [51] A new C and Objective-C language feature named "Blocks" facilitates creation of code that will easily optimize to take advantage of Grand Central Dispatch. [52 ...
