Since I've updated to Sierra and started using XCode 8, XCode started freezing a lot, specially (but not only) when saving. The beachball appears and nothing can be done in XCode.
Sometimes it freezes for some seconds and resumes, other times it won't resume (or at least, not in a reasonable time).
Already tried XCode 8.1 and 8.2. Same problem.
Is there any fix? Or anyway to troubleshoot this (like logs and such).
I've experienced both the -112 and less often the -128 and submitted the error logs to engineering. I was told to contact AppleCare for hardware diagnosis and support.
It's estimated that the logic board would be replaced for $300 so I'm letting it ride a bit to make sure it's really not software before repairing that one machine.
High memory usage is not a reason for a machine to randomly restart, but if you say the memory usage has an effect on the frequency of it happening, the issue might be a defective RAM. There are several tools to test your RAM, a free example would be MemTest86.

Note: Xcode will be reset to its default settings. This might help if you would like to do so.
