iOS 15 中 Swift 和 SwiftUI 的使用情况-51CTO.COM

iOS 15 于 2021 年 9 月发布。但你知道 iOS 15 有多少个二进制文件吗?它使用了哪些编程语言来开发这些应用程序?有多少应用程序是用 Swift 编写的?Apple 是否为某些内置应用程序采用了 SwiftUI?

近日，开发者通过分析 iOS 15 的内置应用得出了结论(这里开发者分析的 iOS 指内核之上的一切东西，不包括 XNU 内核和底层固件)。

iOS 15 中的 Swift 和 SwiftUI

iOS 15 包含 114 个使用 SwiftUI 的二进制文件，几乎是 iOS 14 的 3 倍。同样，包含至少一行 Swift 代码的二进制文件的数量在 iOS 14 和 iOS 15 之间多了差不多两倍：

如图表所示，Apple 继续在其内置应用程序中逐步采用 Swift。今年也是采用 SwiftUI 的重要一年。一些广泛使用的应用程序现在似乎在 iOS 15 中使用 SwiftUI：

Books
Maps
Notes
Weather
Tips
Music
Podcasts
FaceTime? (InCallService)
AppSettings?

还有在 iOS 15 之前就已开始使用 SwiftUI 的 5 个应用：

Translate
Shortcuts
Phone
AirPods Connect Pop-up? (SharingViewService)
Lock Screen? (SleepLockScreen)

其他使用 SwiftUI 的二进制文件主要是小部件或新框架。下面是使用 SwiftUI 的 114 个二进制文件的完整列表：
