What is Swift?

Swift is a multi-paradigm, all-purpose, compiled computer programming language that is developed by Apple Inc. for iPadOS, iOS, macOS, tvOS, watchOS, Linux, and z/OS. Swift is designed and developed to work with Apple's Cocoa and Cocoa Touch frameworks and the large body of pre-existing Objective-C code that is written for Apple software products. Swift is built with the open-source LLVM compiler framework and it has been included in Xcode since its 6th version, it was released in 2014. On Apple platforms, it makes use of the Objective-C runtime library which allows Objective-C, C, C++, and Swift code to run inside one program

Swift is the product of the latest research on software programming languages, coupled together with decades of experience of building Apple platforms. Named parameters are declared in a clean syntax that makes developing APIs in Swift even easier to make use of and maintain. Even better, with swift, there is no need to type semi-colons. Inferred types make code to be cleaner and less prone to mistakes, while modules remove the headers and offer namespaces.

Apple proposed Swift to offer support for many-core concepts that are associated with the Objective-C programming language, notably dynamic dispatch, extensible programming, widespread late binding, and similar features, but in a "safer" way, therefore making it very easy to catch bugs in the software; Swift has various features that address some basic programming errors such as null pointer dereferencing and it provides syntactic sugar to help developers avoid the monument of doom. Swift promotes the notion of extensibility of protocols, an extensibility system that can be applied to structs, types, and classes, which Apple advertises as a real change in regular programming paradigms they term "protocol-oriented programming" (which is very similar to traits).

Swift 4 comes with a playground feature where software developers can write their code and run it to see the results instantly. The first public release of Swift was published in 2010. It took Chris Lattner almost 14 years to come up with the first public official version, and later, it was supported and sponsored by many other contributors. Swift designers took their ideas from various other popular programming languages such as Rust, Objective-C, Haskell, Ruby, C#, Python, and CLU.

Features of Swift

There are many features of Swift and some of them are:

1. Swift has closures that are unified with function pointers.

2. Swift has tuples and they return multiple values.

3. Swift comes with Generics.

4. Swift has a Fast and concise iteration over a range, list, or collection.

5. Swift has structs that have various support methods, extensions, and protocols

6. Swift has functional programming patterns, e.g, map, and filter.

7. Swift comes with a powerful error handling feature built-in.

8. Swift has an advanced control flow with, defer, guard, and repeat keywords.

Benefits of Swift

There are many benefits of Swift and some of them are:

1. Swift has an awesome Open-Source Community.

2. Swift codes are easy and readable.

3. The maintenance of Swift codes is easy.

4. Swift codes allow for speedy App Development.

5. Swift programs are compatible with Objective-C.

6. Programs that are written with Swift are less prone to errors.

7. Swift programs are supported by multiple devices.
