Objective-C comparison to C++

Swift is a compiled programming language created for iOS, OS X, watchOS, tvOS and Linux development by Apple Inc. Swift is designed to work with Apple's Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C code written for Apple products. Swift is intended to be more resilient to erroneous code ("safer") than Objective-C and also more concise. It is built with the LLVM compiler framework included in Xcode 6 and later and uses the Objective-C runtime, which allows C, Objective-C, C++ and Swift code to run within a single program. A second free implementation of Swift targets Microsoft's Common Language Infrastructure (a.k.a. .NET) and the Java/Android platform.

Swift Programming

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.

Objective-C is an object-oriented programming language that is a strict superset of C (any valid C code is equally valid Objective-C code), and it inherits its object-oriented capabilities from Smalltalk. All procedural syntax is identical to that of C, and all object-oriented syntax is an implementation of Smalltalk messaging. It is the main programming language used by Apple for OS-X and iOS and their respective APIs/ Objective-C inherits the syntax, primitive types, and flow control statements of C and adds syntax for defining classes and methods.
