Ok I managed to get it up and running by deleting ~/Downloads/Xcode_10.3.app/Contents/Developer/usr/lib/libMainThreadChecker.dylib It compiles my project.
To be safe, I have copied this same dylib file from latest Xcode 12.2 and put into that folder. It is still working so far.
I had the same problem, I initially solved it using
defaults write com.apple.dt.Xcode DVTDisableMainThreadChecker 1
. After this, Xcode 10 seemed to work on macOS 11, and everything would build from within Xcode.I then had the weirdest issue – when compiling from the command line using
xcodebuild
, the whole machine would grind to a halt and eventually hang, requiring a "hold down the power button" restart. The problem turned out to be thatibtool
(used for compiling IB files) was not honouringDVTDisableMainThreadChecker
, and was still crashing. This was somehow causing the machine to get into a state where it stopped responding.The solution was to copy libMainThreadChecker.dylib from Xcode 12 into the Xcode 10 package. After that the problem went away.
