An Introduction to the Swift Programming Language in 2023

Swift programming language was created by Apple Inc. for iOS and OSX development in 2014. Swift was designed to make programming easier, more expressive, and more efficient than Objective-C. In this article, I’ll share my experience with the Swift language which includes both its pros and cons. Hopefully, this will be helpful for you when deciding about your career path. If you liked reading this post, please share it with your friends. Maybe your friend would like to give Swift a go too? It’s time to get started!

What is Swift and why should you use it?

Swift is a general-purpose programming language developed by Apple and open-sourced in 2015. It is used to build native applications for Mac OS, iOS, Watch OS, and tvOS. Swift offers powerful features that make it easy to write software that’s fast and reliable.

History of Swift Language

Swift was announced at Apple’s developer conference in 2014. It is expected to replace Objective-C as the primary programming language for developing iOS app, macOS, watchOS, and tvOS apps. The first version of Swift was released at WWDC (Worldwide Developers Conference) in June 2014.

The second version of Swift was released at WWDC 2015. This update included new features, like support for Linux and a new playground feature that allows developers to run code without having to create an app. The third version of Swift was released at WWDC 2016. This update included significant improvements to error handling and the introduction of nullability annotations.

The fourth version of Swift was released at WWDC 2017. This update included a number of improvements, including support for ABI (application binary interface) stability across revisions and new features like first-class module support.

The fifth version of Swift was released at WWDC 2018. This update included improvements to Swift’s standard library, support for Linux on IBM POWER servers, and new features like conditional conformances and nested generics.

The sixth version of Swift was released at WWDC 2019. This update included improvements to error handling, the addition of a new syntax for deferring initialization to the moment when your app is launched or opened from cold storage, and support for Objective-C generics in Swift.

The seventh version of Swift was released at WWDC 2020. This update included improvements to the compiler, support for new platforms like macOS Catalina, and enhancements to Swift’s standard library.

Swift Pros

Swift is a general-purpose programming language developed by Apple Inc. for iOS, macOS, watchOS, tvOS, and Linux. It was released on June 1st, 2014 as part of their Xcode IDE.

Swift has been designed to work with Apple’s Cocoa and Cocoa Touch frameworks so you can write apps that run on iOS devices; however, it can also be used in other environments such as Xamarin Studio (Android) or Eclipse (Windows). Swift is an object-oriented programming language which means that it allows the creation of classes and functions with specific characteristics such as data types etc.

Perfect Choice for MVP (Minimum Viable Product) Development

Swift is perfect for MVP development because it provides you with the ability to quickly prototype your app. With its dynamic typing and syntax, developers can easily create an application that uses code snippets without having to worry about errors being thrown. This makes Swift a great choice for those who want to get their ideas off the ground quickly.

It’s fast and very efficient.

Swift is a fast and efficient programming language. It has been designed to be both concise, readable, and easy to use.

Swift uses the LLVM compiler technology which is known for its high performance as well as great optimizing ability. The Swift compiler can compile your code into native machine code on a 64-bit ARM processor or 32-bit x86 processor with no additional configuration needed by you.

With this incredible performance, you will be able to achieve better results with your applications than in any other language that you are using now

It’s very secure.

Swift is a strongly typed language and it makes code safer. It uses type inference, which can make it harder to write code that is type-safe. The compiler will infer types from the context of each line of code (e.g., you’re told what type of variable you’re working with).

It also uses optional in its programming language, which ensures that values are not nil when passed as arguments or returned from functions or methods. This helps prevent errors like “nil” being passed as an argument without checking whether there was any existing value before calling a function or method on it (which could lead to crashes).

Swift is a great option for native development because it’s fast, flexible, and easy to use. It has a clean syntax that makes it easier to read than Objective-C, which makes code more readable and maintainable. This is important when you’re working with large teams of developers who need to understand each other’s work.

Swift is also easier to learn than Objective-C, so it’s a good choice for new developers who are just starting out in the industry. It has a relatively low learning curve and doesn’t require as much time investment as other languages, which makes it ideal for small teams that need to get up to speed quickly.

Swift Cons

Here are some disadvantages of using swift for app development.

Inconsistent syntax

Swift is a very strict language. It has a lot of rules and it’s easy to get them wrong. The Swift community has also been known to be quite opinionated about how you should write code, especially when compared with other programming languages like Java or C++.

This might seem like a negative thing at first glance, but in practice, it means that there are fewer errors in your programs because the compiler will catch most issues for you before they become problems for users (or even worse: bugs).

Lacks reflection capabilities.

While Swift is a great language for writing apps, it lacks the power of reflection. Reflection allows you to examine your code at runtime and dynamically change it. For example, if you have a function that calculates some data and then uses that data in another function, it would be useful for this second function to know about the first one so that it can use its results without having to recheck them or worry about updating the values each time they change. You could do this by using reflection:

“`swift let calcSomeNumbers = { let numbers = [1,”apple”:”apple”] as [String] return numbers[0] + ” apples” } “`

The code above shows how we can use reflection in Swift (and other languages). Here’s what happens when we execute this program:

1) We create an anonymous struct variable called “calcSomeNumbers” which stores all its members inside of it;

2) Then we assign two variables whose types are not known until runtime 3) Finally we call our new variable “calcSomeNumbers” with no arguments

4) The result should be 25 because there are two parameters named “apple” which take direct objects (string arrays).

Limited runtime introspection.

  • Swift has a limited runtime introspection.
  • Swift does not have reflection capabilities.
  • Swift does not have dynamic dispatch.
  • Swift does not have dynamic typing.

Swift is a fun programming language to learn, and it’s capable of expressing text in potentially interesting ways. It’s also very secure, fast, and efficient.

Cons of Using Swift for iOS Native Development

Swift is not a good programming language for beginners. The syntax is very different from C and Objective-C, and it takes time to get used to it. Swift was designed as a replacement for Objective-C, which means that all of your existing iOS apps will need to be rewritten in Swift before they can be deployed on the App Store. This can take months or even years if your app has a lot of legacy code.

Pros & Cons of Swift Programming Language in 2023

Swift is a great choice if you want to build a small, simple app. Swift is great for writing small apps and prototypes. But it’s not an ideal choice for large projects with lots of legacy code. If you’re thinking about building something that will take more than several months to complete. Stick with Objective-C or Java instead.

If you’re just started, it can be tempting to want to use the latest and greatest technology. But it’s important to think about. How much effort do you want to put into learning a new language before jumping in? If you only need a simple app that takes a couple of months to build, Swift is probably not the best choice.


With Swift, you can write fast apps that work with iOS and macOS. If you’re new to programming, this is a great language for you to learn. It’s also going to be the default language of Apple’s next major release, so it has a lot of momentum behind it. You can write apps for both iOS and macOS, and it’s a great way to get started with programming. It’s also very secure, fast, and efficient.
