Hi @xta0,
Thanks! That did it. The build worked this time 
I’m running up against another issue now though… not sure if it’s because I was messing around with Eigen libraries earlier or not… but I’m getting these math errors after importing pytorch into my XCode library.
.../pytorch/include/caffe2/perfkernels/math.h:3:10: 'cstdint' file not found
.../WatchSimulator6.1.sdk/usr/include/dispatch/dispatch.h:25:10: Could not build module 'Darwin'
.../WatchSimulator6.1.sdk/System/Library/Frameworks/Foundation.framework/Headers/Foundation.h:6:10: Could not build module 'CoreFoundation'

I’ve uninstalled and re-installed XCode as per some Stack Overflow posts I’ve found with similar issues and no luck.
Any ideas?
Thanks again for responding!
