When I try to run my app on my device Xcode gets stuck on processing symbol files.
I restarted the machine (I'm using VirtualBox), tried a different USB port, restarted the host computer, cleaned the build folder, tried a different project, updated Xcode to 8.2, tried to use Xcode 7.3 but nothing worked. My device does show in iTunes.
I left iTunes open when I tried to run it on my iPad and then it said "Unable to copy symbol files - unable to read required data from device"
Xcode 8.2 (latest currently) and iOS 10.1
Today I have solved exactly the same problem. I think the main problem is in VirtualBox USB controller. Go to the settings of your virtual machine, select USB and you will see 'USB Controller 1.1 (OHCI)' by default. You have to select 'USB controller 2.0 (EHCI)'. I have: - VirtualBox: 5.1.12r112440 (Qt5.6.2) - macOS Sierra 10.12.2 with the latest updates. - XCode 8.2 - iPhone 5, iOS 10.2
Be sure that: - You have original lightning cable - You can see your iDevice in iTunes - Try to restart your MAC and iDevice
