You can connect quite a few things via the Camera Connection Kit (CCK) which has a USB port in it. MIDI controllers and USB soundcards are two things I've used recently.

  Not sure what’s the CCK. Is it one of the dongles they sell with HDMI, SD Reader, and USB? I first got excited that it can connect to USB webcams — I have some modded webcams I use as microscope — would be super useful if I could interface it with a camera app. But it didn’t work, last I tried. Are you aware of some way to do that? :)

    I haven't heard of any webcams that work in iOS via the CCK - sorry! I'm not too familiar with how it all works, but I imagine it has a lot to do with the individual apps that are running to be able to read/write to the USB port.

      Seems like it, thanks anyway! Maybe now that there’s USBKit (although not sure if it’s MacOS only), one might be able to work out a camera driver implementation. Yay, weekend project!

        USBDriverKit is macOS only.

    I believe they're talking about the "Lightning to USB 3 Camera Adapter."[0]. I have one of these and so far I have only used it to plug into my DAC[1] so I can use Apple Music on an old iPhone with a real HiFi, but I think this has been the preferred way to connect to multimedia stuff for a while. A long time ago on an iPad now far far away, I had the cordless little SD card reader, but the iPad itself wasn't much use for editing RAW photos in that generation.

Interesting implementation tidbit from a Federighi interview: >From a security architecture point of view, we did not want to have file system drivers running in the kernel communicating with external media that could have been tampered with. Getting all of our file systems to be isolated from the kernel, it was real hardcore engineering efforts.

I’m pretty sure the USB stack was there all along, they just kept it to themselves. Just like how the iPhone baseband chip would be capable of receiving FM radio, they just don’t want to enable it.
