Top 10 Popular Apps Built with Swift


According to Statcounter, Android dominates the global mobile OS market share with 71.45% while iOS holds 27.83%. However, in the United States, iOS accounts for 57.43% of the mobile OS market share and Android at 42.29%.

With a recent survey revealing more people switching from Android to iOS, no wonder why startups and mature enterprises invest heavily in iOS app development.

Since its launch, Swift has become a go-to language for building iOS applications. Swift brings all the advantages of developing top-notch, custom-tailored and highly functional iOS apps that help businesses enhance their bottom line.

Thus, the world’s leading brands such as Lyft, Airbnb, WordPress and others made a switch to Swift for their iOS apps.

Through this post, we’ll take a deeper look at these apps built with Swift. But let’s first have a quick overview of Swift and its market usage.

What is Swift?

Swift is a multi-paradigm, general-purpose, compiled and open-source programming language for building apps for iOS, macOS, watchOS, tvOS and Linux.

It was developed by Apple in 2014 to provide developers with a robust programming language for iOS app development. According to, Swift was designed to be fast, safe and expressive.  The programming language adopts the best traits of C and Objective-C but without the constraints of C compatibility.

A Quick Glimpse at the Market Usage of Swift

Before we take a deep look at the reasons why developers and companies alike choose Swift, let’s first take a peek at the language’s market usage.

  • At this time of writing, Swift has 59.5K stars, 9.6K forks and more than 900 contributors on GitHub.
  • According to the 2021 Stack Overflow Developer, 63.59% of developers loved using Swift.

Why is Swift Preferred for iOS App Development?

When it comes to investing in iOS app development, you’ll also have to make a decision between React Native/Flutter vs Swift. In simple words, you need to decide whether to go for a cross-platform or a native app development approach.

If you decide to go for a native app development approach, you’ll come across another decision: Swift or Objective-C.

Well, the aforementioned numbers clearly show the increasing popularity of the brand-new Swift programming language. Now, let’s understand why companies prefer Swift over Objective-C for native iOS app development.

  • Open-Source

As Swift is an open-source and free programming language, it has a decent community of developers and companies alike behind it.

Moreover, the availability of ample resources in the form of blogs, articles and documentation make it easy for even beginners to learn and gain expertise in the language.

  • Faster Development

The Swift programming language has a simple, expressive and clean syntax. That makes it easy for developers to read, write and modify the code. Moreover, concise code ensures a lesser volume of code which translates to reduced development time.

  • Safer

Swift was designed to be safer than C-based programming languages. It eradicates entire classes of unsafe code. It comes along with many safety traits such as automatic memory management and variable initialization.

Also, iOS developers can see any code errors, which reduces the debugging time and eliminates the risk of low-quality code deployment.

  • Enhanced Performance

Besides being faster than Objective-C language, Swift promises an app performance enhancement. According to Apple, Swift is 2.6X faster than Objective-C and 8.4x faster than Python 2.7.

  • Objective-C Interoperability

You can build an entirely new app from the ground up using Swift or use Swift language to implement new features in your existing app. Swift and Objective-C can co-exist in the same iOS app development project.

  • Easy Maintenance

Applications built using Swift programming language are easy to maintain. Compared to Objective-C, which is maintained in two code files, Swift combines the header (.h) and implementation (.m) files in just one (.swift) file.

These were some of the major reasons why Swift and developers with strong expertise in language are gaining immense popularity among companies for iOS app development. Many leading brands are already using it for their iOS applications.
