As with previous iOS versions, let’s analyze the built-in apps of iOS 18 to answer a few questions: How many binaries does iOS 18 contain? Which programming languages were used to develop these apps? How many apps are written in Swift? What percentage of apps use SwiftUI versus UIKit?
Last month, I analyzed the programming languages and UI frameworks used to create iOS 17. This month, let’s analyze macOS from OS X El Capitan 10.11 to the latest macOS Sonoma 14 and answer a few questions:
What is the total count of binaries within macOS Sonoma? Which programming languages are used to develop these apps? How many apps are written with Swift? How many apps are using Mac Catalyst and SwiftUI versus AppKit?
Now that iOS 17 is available, let’s analyze its built-in apps to answer a few questions: How many binaries are in iOS 17? Which programming languages are used to develop these apps? How many apps are written with Swift? What is the percentage of apps using SwiftUI versus UIKit?
iOS 16 was just released so let’s analyze its built-in apps. Like in the past years, I will try to answer a couple of questions: How many binaries are in iOS 16? Which programming languages are used to develop these apps? How many apps are written with Swift? What is the percentage of apps using SwiftUI versus UIKit?
iOS 15 was released a few months ago in September 2021. In this article, I analyze the built-in apps composing iOS 15. How many binaries are in iOS 15? Which programming languages are used to develop these apps? How many apps are written with Swift? Has Apple adopted SwiftUI for some built-in apps?
In my previous article about Apple’s use of Swift and SwiftUI in iOS 14, I counted the number of built-in apps in iOS using Swift and SwiftUI. Several readers asked if I could provide a percentage rather than an absolute number.
In this new article, I will answer this question by measuring the total number of binaries in iOS. I will go one step further and also count the number of binaries using other programming languages: Objective-C, C++ and C.
Finally to be as complete as possible, I ran this analysis on all major iOS releases, from iPhone OS 1.0 to iOS 14. This will provide a detailed overview of the evolution of the different programming languages over more than a decade of iOS development.
Swift was introduced a couple of years ago at Apple’s 2014 WWDC. Over the years I analyzed iOS to measure how many built-in applications were using Swift. iOS 9 released in 2015 included a single application written with Swift: Calculator. Since then this number has grown with each iOS release: iOS 10.1, iOS 11.1, iOS 12.0 and finally iOS 13.1.
iOS 14 is now available so let’s check how this number evolved since iOS 13. Apple announced SwiftUI during WWDC 2019, a year ago. In this article I will also try to measure which built-in apps are using this new UI framework.
