What is swift?

Swift is a powerful programming language made by Apple for creating iOS, Mac, Apple TV, and Apple Watch apps. It is designed in a way that gives developers more freedom than ever. Swift is easy to use and open source, which makes it easy for anyone with an idea to create something incredible.

Although the name is the same, this code has nothing to do with the banking code which is also called SWIFT.

Key features

Here are some of Swift’s many features:

  • Fast and powerful

Swift offers fantastic performance. Built to take advantage of current hardware, it is performance-optimized.

  • Safety

It provides safeguards to prevent errors and improve readability.

  • Modern syntax

The program’s syntax is expressive but concise, and it has the features of a modern language.

  • Interactive playgrounds

Its playgrounds make it very easy for developers to test code and see their results immediately without having to run the app.

  • Open source

Being an open-source language, Swift has a large community of developers.

Swift’s many applications include:

  • iOS and macOS app development

It is mainly used for developing applications for Apple’s ecosystem, which includes the iPhone, iPad, Mac, Apple Watch, and Apple TV.

  • Server-side programming

It can also be used for back-end development, which provides an alternative to more traditional server-side languages.


There are several benefits to using Swift, such as:

  • Developer friendly

It offers a clean and understandable syntax, making it easy for beginners.

  • Performance

Since its focus is on performance, apps can run faster and more smoothly.

  • Community and support

Since Swift is open source, it has a large and active community, offering a lot of resources and help.

  • Compatibility

Swift works side by side with Objective-C, making it easy to integrate with existing projects.

According to eightify.app:
“Swift programming language is worth learning for those seeking a high-paying freelance career.”

There are several challenges an individual might encounter when developing with Swift, including:

  • Limited to the Apple ecosystem

Swift’s main focus is on all the Apple products, which can be a limitation if cross-platform compatibility is needed.

  • Young language

It is still a relatively new language, which means it is still evolving. This can lead to changes in the language that developers might need to keep up with.

The future

The future of Swift is bright:

  • Continued evolution

Given Apple’s significant development investment in Swift, it is expected to continue to evolve.

  • Wider adoption

As the language develops, more people outside the Apple developer community are likely to start using it.
