iOS usb/serial access and use

I've managed, with a lot of help from the community, to get the mergBLE commands and messages working very well between my LC iOS app and an arduino. Now, for the next "component", I'd like to be able to communicate to and from the arduino to and from an iOS device (iPhone or iPad) via a "hardwire" connection... just in case BLE is disconnecting or generally unreliable in certain environments.
I done a fair bit of web searching but cannot find a way to reference the iOS USB via LC. There's info on Linux, Windows and MacOS, but none (that I can find) on iOS. Obviously LC *can* employ the USB on an iOS device.... it does it in its Development / "Test" and "Test Target" functionality to send an app to an attached iOS device.
I've seen a portion of Apple's USB development doc's and spec's ... since I'm not an XCode user, they don't make any sense to me and don't (seem) to indicate any "device name". There are various mentions of "sandboxing" the app and then enabling various "entitlements" ... one of which is " Allow USB Access: com.apple.security.device.usb". I'm totally clueless on this sort of reference.

Windows:
*open* driver "COM2:" for binary update
while on Linux ports are tty (or something similar) into the folder / dev , then:
*open* driver "/ dev / tty2" for binary update
Mac is a bit more complicated, because the name and position changes with each version, however, for the rest it is like on Linux:
# Try one of these: /dev/cu.usbmodem2, /dev.tty.usbmodem2, /dev.cu.usbserial2,
*open* driver "/dev/cu.usbmodem2" for binary update
.... "missing" iOS ...
So ... anyone who can give me a push in the right direction would have my most sincere appreciation. I haven't actually tried the Mac examples but since I'm fairly certain of the very significant differences between MacOS and iOS, I'm skeptical of even trying.... I will and report back here... but I'm not likely to have any success.
Cheers!
