iOS 9.3.1 Xcode 7.3 "Unable to copy symbols from this device"

Question

I was using Xcode 7.2 but then I upgraded my iPhone to iOS 9.3.1 and got the message "Could not find Developer Disk Image". I've seen this many times in my life so I upgraded to Xcode 7.3. Now I get "Unable to copy symbols from this device" I tried the beta seed as well. Any ideas?

Answer 1

Delete app from your device if is installed. Try to reconnect your device and wait for copying symbolic files symbol to complete the process, than clean your project, and relaunch Xcode.

Edit Ensure you have enough space on your mac
