问题
I updated Xcode today (Xcode 11.0), and now it crashes every time I try running any project on my iPhone (iOS 13.1).
Already tried:
- Cleaning derived data
- Cleaning library cache folder
- Uninstalling xCode and downloading it again from the store
- Restarting Mac
- Restarting iPhone
- Reconnecting iPhone trough itunes
The odd thing is that the Xcode activity doesn't show the "installing app" phase, it goes straight to "Running app on device" and then crashes. Running on the simulator works without a problem.
Already searched on the Apple forums and sent the report to Apple, but maybe there is something I can do to solve te issue.

So, I found that inside this folder:
~/Library/Developer/Xcode/iOS DeviceSupport
Xcode creates cache folders for all the physical devices symbols it paired.
This folder remains even if you uninstall Xcode, and the cache is reused even when you install other versions of the software.
Deleting the folders content made Xcode download the symbols again, run prepare debug support for the device phase and reset the device connection, solving the problem.

According to @alxlives 'Deleting the folders content made Xcode download the symbols again, run prepare debug support for the device phase and reset the device connection, solving the problem.' This solution solved the problem for me. Here is a terminal command to remove all contents inside of the folder.
rm -r ~/Library/Developer/Xcode/iOS\ DeviceSupport/
This commands remove all files that are located inside of the Device Support folderl.

I was having this issue with Xcode 11.1 and an iPhone XR running iOS 13.2.3 (iPad running that OS version was fine). The accepted answer didn't work for me. Upgrading to Xcode 11.2.1 fixed it.
