IOKit remains the only way to write kernel extensions, which are still supported but discouraged if DriverKit does the job. NeXtTSTEP using Objective-C for drivers was certainly very cute but I guess they just didn’t want to have driver makers learn the language :(

> Devices supported on macOS 11 and later require DriverKit. Use IOKit in your apps and services to discover and use devices.
