Update 12/6/2023: Although Apple informed us that: “There is no workaround Developer Technical Support can provide”, we found a solution that’s immune to the card contents enumeration bug described below. It is released in ShutterCount Mobile 6.5.1 and ShutterCount Pro Mobile 6.5.1.
It seems Apple will also fix it in iOS/iPadOS 17.2. Please update your software accordingly. The next update to Kuuvik Capture will also contain our solution – as well as many other exciting things.

While most professional users know that you should NEVER EVER install a dot zero version of any operating system on production devices, and that you have to evaluate all your apps on a new operating system before moving to it, I’m going to save you save some time by discussing why you should avoid updating to iOS/iPadOS 17 in case you rely on Kuuvik Capture or ShutterCount – or any other USB tethering/remote control app.
There are two separate issues. There are also workarounds for them, but that doesn’t mean they aren’t a pain in the ass.
Card contents enumeration is stuck at 0% when there are no images on the card, or no card in the camera
Due to peculiarities of iOS USB tethering that Apple mandates, we must enumerate card contents before connecting to a Canon EOS camera. Otherwise the camera would almost certainly crash with an ERROR 70. But in iOS 17 that enumeration never completes when you have no card in the camera or have an empty card.
And you will be greeted with the stuck progress indicator that you see on the screen shot on the right, followed by an error message that the connection cannot be established.
The workaround is to have at least one image on the card, in which case iOS will be happy to go ahead with the connection.
Apple Lightning to USB Camera Adapter works only if you connect the USB cable to the adapter last
If you do not obey this rule, iOS 17 will not detect the camera at all. Not even in Photos, or in any other app.
That is, you must remember to do the follwing: 1) connect the adapter to your iPhone/iPad, 2) connect the USB cable to the camera, and lastly 3) connect the other end of the USB cable to the adapter.
