Am I the only one with Xcode hanging?

Question

macOS

Recently updated Xcode to version 6.2 (6C131e), the most recent update. After that, at some point, the program starts to eat up all the resources of the processor, the system hangs hard, reacts to any actions with a minute delay. Do I have one? Anyone know how to fix it?
UPDATE
The problem was solved in an unexpected (for me) way. At first I tried to reinstall, to no avail. Then I got into the Preferences folder and deleted from it all the settings files where "xcode" was found. Unexpectedly, it worked, and quite well. Not the fact that the problem is completely fixed, but within half an hour of work no problems were found, everything runs smoothly, even the iOS emulator.
The question is still open if someone else encounters a similar problem and finds its cause. Thank you for attention.
