Swift is a programming language created in 2014 by Apple Inc. It works properly in both the company's systems: macOS, iOS, iPadOS, watchOS, tvOS, as well as on Linux and Windows. It was developed to significantly lower the threshold of entry into programming for a new generation of programmers, providing many facilities and built-in, multi-level structures ready for use in almost any project. In turn, its syntax is similar to that of C# or Java, as well as Kotlin.
Swift - Apple's programming language
Swift replaced the Objective-C language previously used by Apple, and its syntax, which can be read like text written in English, allows you to write applications for modern watches, smartphones, TVs, as well as laptops, computers and servers. Its undoubted advantage is that it is highly resistant to errors that a programmer can make while working, as it has built-in mechanisms to catch any inconsistencies in the code. Originally, in order to create modern applications, it was necessary to use hardware from Apple, the price of which was often prohibitive for self-taught developers. Fortunately, today a much cheaper alternative is Hackintosh, which also run the macOS operating system.
Swift allows you to write applications in several paradigms: declarative, reactive, protocol and functional. It also has many functions specific to high-level languages, e.g.: filter, map and reduce, which greatly speed up and simplify the work of developers. Due to its stability and association with one of the most recognizable companies in the world, which is undoubtedly Apple, the language is one of the fastest growing programming languages, and the demand of the global market for Swift specialists is constantly increasing. Other advantages of this language are its open code available to all and its high performance thanks to its simple and concise syntax. Also, it supports the security of applications developed in it, as clean and consistent code prevents errors and improves readability, which allows to catch them quickly.
