Hi, We were planning on using DriverKit to develop a USB Driver on IOS for iPhone. Within the DriverKit website, it say 'IOS16.0+' which lead us to believe it was compatible with iPhones running IOS16.0+. However, it appears DriverKit is only available for iPads running iPadOS, and computers running macOS. Are there any alternatives that would allow us to create a device specific USB driver for an iPhone running IOS?

I have reference some related post for this issue: https://developer.apple.com/documentation/xcode-release-notes/xcode-16-release-notes#Foundation https://developer.apple.com/forums/thread/762711 Unfortunately, I'm facing the similar issues even though using Xcode Version 16.2 (16C5032a). we have the following build environment: Xcode version: Xcode 16.2 (16C5032a) macOS Version: macOS 14.7.4 (23H420) Everything builds and install fine. But when attempting to plug on Device on macOS 14.7.4 it crashes immediately with what appears to be a missing Foundation symbol.
