    What version of macOS X are you running? A poster in this thread at Apple Forums says that upgrading to Sierra fixed the problem. And this: "In my case, I noticed that if you set the root view's Top Bar value (Attributes Inspector > Simulated Metrics > Top Bar) from Inferred to Opaque Navigation Bar, it turns into hogging mode. Everytime you switch to this Nib file, your CPU usage turns up. Switching the value back to its default seems to resolve it."

    Kill the ibtoold and xcode processes, then report back what happened.

Did they finally disappear? I suspect it was updating/recompiling your Xcode interface files and once done, these processes should go away.

  • killed all the processes but xcode is still slow responsive. May be it's an issue with xcode 8.2
