What is Swift?

Swift is a powerful programming language designed by Apple for use on iOS, iPadOS, macOS, tvOS and watchOS operating systems. The language uses concise code and simple syntax to make it easy to work with, scalable and approachable for newer developers.

What programming language is used in Swift?
Answer Part 1

Swift is, in itself, a programming language but can be viewed as a successor to the C and Objective-C languages.

Answer Part 2

Swift supports many of the core concepts found in Objective-C, such as dynamic dispatch, widespread late binding and extensible programming but was designed to do so in a way that makes it easier to catch software bugs, which creates a safer overall language.

Swift also uses Objective-C runtime libraries, allowing the language to run alongside Objective-C, C and C++ code within the same program.

Is Swift similar to C++?
Answer Part 1

Swift shares much of its functionality with C++, but both excel in different areas and are used in different environments.

Answer Part 2

Although both Swift and C++ are object-oriented programming languages, the two excel in different areas, with the biggest difference being that Swift is used to develop applications intended for Apple’s MacOS and iOS operating systems while C++ may be used for web and Android applications.  Swift is an evolution of Objective-C, whereas C++ is an evolution of C programming, causing key differences in functionality. C++ is known to many for its excellent performance and is typically somewhat faster than Swift code but due to Apple’s OS dominance in the mobile space, creating mobile apps with C++ may be futile.

What are the benefits to using Swift?
Answer Part 1

Swift is a clean and expressive language that uses concise code, simplified syntax and grammar, making it easier to read and write.

Answer Part 2

Swift uses concise code, simplified syntax and eased grammar to make the language easy to write and understand, making it adaptable for developers of all skill levels. Although a newer programming language that originated in 2014 for use on Apple devices, Swift can now be used on Windows and most Linux-based operating systems, though this practice is still uncommon.

Swift’s use of Objective-C runtime libraries on Apple platforms allows Swift, C, Objective-C and C++ code to all run within the same program, boosting the performance of C to an even greater level. 

Other areas where Swift excels include memory maintenance, overall speed and binary compatibility, as well as its cross-platform, open-source nature.
