My IPhone 5s not showing in xcode Version 8.3.2 (8E2002), but it does show in system information > USB 3.0 Bus. It also does not show up in ITunes.
I have tried restarting my mac and my iphone. I have tried all the thunderbolt 3 ports on my macbook pro (the new 15"). I have done all which is listed here: https://support.apple.com/en-us/HT204095. That site now tells me to contact support, so here I am.
I am plugging the iphone in with the folloing hardware from my mac:
1. Apple usb-c to usb adapter
2. non-apple-brand usb to iphone ligtning cable.
3. Apple iphone 5/5s/se doc
This has worked before. I just recently updated my xcode, which I suspect caused this problem.
