Swift incorporates innovations and conventions from various programming languages, with notable inspiration from Objective-C, which it replaced as the primary development language on Apple Platforms. Swift was designed to be safe and friendly to new programmers while not sacrificing speed.
This included Objective-C, NeXT's Objective-C-based developer tool, Project Builder, and its interface design tool, Interface Builder. Both were later merged into one application, Xcode. Most of Apple's current Cocoa API is based on OpenStep interface objects and is the most significant Objective-C environment being used for active development.
Cocoa is Apple's native object-oriented application programming interface (API) for its desktop operating system macOS.. Cocoa consists of the Foundation Kit, Application Kit, and Core Data frameworks, as included by the Cocoa.h header file, and the libraries and frameworks included by those, such as the C standard library and the Objective-C runtime.
In order to test applications, get technical support, and distribute apps through App Store, developers are required to subscribe to the Apple Developer Program. Combined with Xcode, the iOS SDK helps developers write iOS apps using officially supported programming languages, including Swift and Objective-C. Other companies have also created ...
Swift can import any C library, optionally annotating C headers to map C types to Swift objects [27] and import libraries as Swift modules. [28] Swift has two-way bridging with Objective-C on platforms which support Apple's Objective-C runtime. Unlike Objective-C, Swift does not currently support C++ interoperation or exposing Swift types as C ...
In contrast, native environments are targeted at one platform for each of those environments. For example, Android development occurs in the Eclipse IDE using Android Developer Tools (ADT) plugins, Apple iOS development occurs using the Xcode IDE with Objective-C and/or Swift, Windows and BlackBerry each have their own development environments.
Over time, Lattner built out the technology, personally implementing many major new features in LLVM, formed and built a team of LLVM developers at Apple, started the Clang project, took responsibility for evolving Objective-C (contributing to the blocks language feature, and driving the ARC and Objective-C literals features), and nurtured the ...
The Foundation Kit, or just Foundation for short, is an Objective-C framework in the OpenStep specification described by NeXT Computer, Inc.. It provides basic classes such as wrapper classes and data structure classes. This framework uses the prefix NS (for NeXTSTEP [1]). It is also part of Cocoa and of the Swift standard library.
