I got the new beta today and simply having the app open consumes all available CPU, while doing absolutely nothing. Is this everyone's experience? I saw a video someone did on a freshly booted 15" MacBook Pro (Late 2013) https://vimeo.com/220489
This video corroborates my experience. Just curious if it's a known things and how to remediate.

I have experienced this as well. Sometimes it works fine, but most of the time when I've tried to write some code in it it would consume all of my CPU. I'm running it on Early 2013 MacBook Pro 15".
I'm having this problem on one of my computers too (Macbook 12" running 10.12). This makes working from battery power impossible.
Sampling the process shows Xcode is busy indexing documentation. It's probably stuck in some sort of loop, since this process never seems to complete. I'm not seeing this behavior on my other Macs running the Xcode beta.
I've deleted Xcode caches, and everything in ~/Library/Developer/, to no avail.
Be sure it's not busy downloading components/docs etc. New Xcode installs always show a cpu load spike right after first run...
Best to leave it alone until all such housekeeping is complete.
