You were able to connect the 70D to an iPhone 12?
What app were you using? I believe the Canon Connect app is strictly wireless. You would connect via Wi-Fi or Bluetooth. The app does not work on USB, AFAIK. I recommend using Bluetooth.
Upgrading a cable or even a lightening cable adapter to use USB-C should be simple enough. I don’t know why cable manufacturers haven’t done it yet since Canon is now using using USB-C connectors exclusively.
