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?
If you followed the recent Apple events, you probably saw a picture of the A14 and M1 dies… that got me thinking about what you would see if you could pass iOS under X-Rays…
In my previous article about the evolution of the programming languages from iPhone OS 1.0 to iOS 14, I analyzed iOS based on the number of binaries and their programming languages. As I pointed out in this past post, the size of the binaries were not taken in account. In this new article, I look at iPhone OS 1.0 and iOS 14 from a size perspective using tree maps.
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.
Assiduous readers of this blog might have noticed a significant drop in the number of articles last year. Couldn’t I find any interesting subject? Was I getting lazy? Hell no!
Today I am pleased to release Clatters for iOS and iPadOS. Clatters is an app to easily monitor in one place your brand, product or any other keyword on your favorite social networks - Reddit, HackerNews and even comments on the iOS App Store.
Swift was introduced at Apple’s 2014 WWDC and it is interesting to measure Apple’s own use of Swift in iOS over the years. iOS 9 released in 2015 included a single application written with Swift: Calculator. Since then the number of applications using Swift in iOS has grown each year with iOS 10.1, iOS 11.1 and iOS 12.0.
Now that iOS 13.1 is available, let’s measure how many applications are using Swift this year.
libMobileGestalt is a private library in iOS that describes the capabilities of the device: system version, build version, device type, device features, status of the airplane mode, …
Apple obfuscates this information which makes it hard to know the capabilities of the device. In January 2017, I presented a method for Deobfuscating libMobileGestalt keys. At that time there were 673 known obfuscated keys and I managed to recover 564 out of the 673 keys (83%).
Since this previous article, Apple has released 2 major iOS versions, and new obfuscated keys have been added. In this post I quickly recap what is libMobileGestalt and provide the updated list of recovered keys.
Two years ago I measured Apple’s use of Swift in iOS 10.1 and last year I counted how many applications were using Swift in iOS 11.1.
This year I’m analyzing iOS 12, released by Apple this month.
