Hi everyone, I'm working with a third party to integrate their USB driver into our app and I'm wondering if iPadOS supports bundling a prebuilt .systemextension file with the entitlement com.apple.developer.system-extension.redistributable into our app that has the com.apple.developer.driverkit.communicates-with-drivers entitlement?
If not, is there a way to bundle a third party USB driver into our iPad app?

No.
For a start, the docs for com.apple.developer.system-extension.redistributable list it as macOS only.
But regardless of that, App Store re-signs apps during the submission process, so it’s literally impossible for an iOS app to have different parts signed by different developers, because once the app gets to the device it’s actually all signed by Apple.
Having said that, there’s nothing to stop you from getting a pre-built sysex from a vendor, signing it with your distribution signing identity, and embedding that in your iOS app. However, there is a significant drawback here: The sysex needs managed entitlements to work correctly and those are granted on a team-by-team basis. So, if your sign the code as your team, you’d need to apply for those managed entitlements. On macOS you can sidestep that using com.apple.developer.system-extension.redistributable, but that’s not available on iOS.
Share and Enjoy
