Earlier it was said that in macOS a system tray was written on Swift. Interesting how much Swift in the new OS Big Sur. And what exactly have done on it?

Apple doesn’t publish hard numbers but there have been various third-party attempts to analyse this. I don’t know of one for macOS 11 but [here’s one](https://blog.timac.org/2020/0927-state-of-swift-ios14/) for iOS 14.
