Features Of Swift Programming Language

Swift Training


Swift is an advanced programing language that Apple Inc. has developed to develop various iOS applications efficiently. This programming is powerful, intuitive, multi-paradigm, and incorporates the best features of C and Objective-C. Swift is extensively used to develop applications that run on iOS, OS X, tvOS, and watchOS. Swift was first launched in 2014 and has emerged as one of the most widely used programming languages to develop iOS applications. This programming language is highly readable, offers dynamic libraries, supports interactive coding, and speeds up the app development process. It is a clean programming language that supports Linux development, excellent and fast data management and provides easy maintenance. In addition, Swift is an interactive and open-source programming language that facilitates high-speed functioning, offers enhanced safety, and several development tools that make the application development processes faster and more effective. Skills in Swift are a major prerequisite for iOS developers. Therefore, many training institutes offer Swift Online Training to help aspiring professionals learn more about this platform and enhance their application development skills.

This blog explains the different features of Swift. Read on to learn more.

Swift Features:

Swift is a robust programming language offering several tools to simplify application development.

Let us look at the different features of the Swift programming language in detail.

  1. The Automatic Reference Counting (ARC) feature in Swift determines and eliminates the instances which are no longer used.
  2. The Function Pointers in Swift contain the address of specific functions and point to the “code vs. data” to signify a behaviour by calling the function rather than writing codes.
  3. The Swift programming language allows users to return multiple values from functions using the Tuples feature. The Tuples are unchangeable or fixed sets of elements in Swift that are arranged in a sequence.
  4. The Generics feature in Swift is used to find code errors by enabling the types that can be used as parameters. In addition, Generics allows users to write reusable codes.
  5. The Swift programing language supports faster and more concise iteration over a range or collection. This platform knows the kind of data an array holds and can quickly run blocks of codes by assigning every element a constant.
  6. The Structs in Swift support various methods, extensions, and protocols. This enables Swift users to add additional functionality using extensions, including the option to extend types even if you lack access to the original code source.
  7. The Functional Programming Patterns in Swift takes in the array, computes the value, and creates a pattern that is then returned to the code that called for the action.
  8. Swift has several powerful in-built error handling features that help detect the errors in the platform effectively. The Swift programming language offers error-handling methods like throwing, catching, propagating, and manipulating recoverable errors at runtime.
  9. Swift uses Flow Statements to control the flow of a program. This programming language uses different statements, like the Control Transfer Statements, Loop Statements, Branch Statements, Do Statements, Defer Statements, etc., to facilitate application development.


To sum up, Swift is a highly-level programming language by Apple Inc. This programming language is used to develop applications that run on iOS, OS X, tvOS, and watchOS. Swift is a highly readable and clean programming language that offers dynamic libraries, supports interactive coding, and speeds up app development. Various benefits have made Swift one of the most widely sued programming languages for iOS development. Therefore, aspiring iOS developers must consider joining the Swift Course in Noida, as this programming language is vital to iOS applications. Some common features of Swift include Automatic Reference Counting (ARC), Function Pointers, Tuples, Generics, Structs, Functional Programming Patterns, error handling features, Flow Statements, etc.
