With just some boxes geometry and the sky set to invisible, this eats 100 % CPU.
Not in play mode, just editing.
Is this expected behaviour?
(iMac, OSX Maverick)
Anyone in charge for this?
My system:

XCode shows 100% usage or what? On my computer xcode also shows over 100% cpu usage but same time it shows over 600% as free, so in reality it uses only about 15-20% of my cpu capacity.
Talking about activity monitor. The main loop of the editor should not eat 100%, when doing just basics. Question is NOT related to XCode.
Activity Monitor can be a bit misleading. As juniperi mentioned, when it shows that a process is using 100%, it means a 100% of a single core. On your i7 CPU, which has (I suppose) 8 logical cores (you can check that in Activity Monitor’s Window->CPU Usage), the actual CPU usage is most likely about 13%.
