The debug view hierarchy tool in Xcode 7.3 only works on iOS 9.3 simulators. When I try to use it on iOS 8.2 simulators, the debug view is a blank white screen. Does anyone else see this?
Unfortunately, I see the same thing - just a blank screen when (8.4) simulators work (in my case), but it works fine w / iOS 9. This is especially annoying because the problem I'm trying to debug behaves differently on iOS 8!
I am on Xcode 8.2, but I had the same problem.
I used the "Nvidia Web Driver" and not the default graphics driver for OS X. When I switched to the OSX driver and rebooted, this function started working for me again.
If you are using the "Nvidia Web Driver", you can use the following kext below.
NVWebDriverLibValFix mologie
run this command and restart:
sudo tar -xv -C /Library/Extensions -f ~/Downloads/NVWebDriverLibValFix.kext.1.0.0.tar.gz sudo kextutil /Library/Extensions/NVWebDriverLibValFix.kext
I found that on a system that does not support Airplay (older Mac Pro), it does not work. On what Airplay supports, everything seems to work just fine.
