   tl;dr - I was seeing this error when I tried to run my flutter app on the simulator in VS Code. I unplugged an old iPod Touch (4th Gen) and rebooted my computer and the issue went away.

   More Info

   I was getting the error:

   flutter ideviceinfo returned an error: ERROR: Could not connect to lockdownd, error code -17
   

   Running ideviceinfo -d produced similar errors on its own too.

   I hadn't seen any updates to flutter or plugins and was working just fine this morning. The only thing I had done different was to plug an old iPod Touch 4th Gen into laptop.

   Tried the steps above and it didn't resolve the issue for me.

   flutter doctor -v:

   Unplugging the old iPod and rebooting resolved the issue.
