Xcode 9 Beta 5, 137% CPU Usage?

Hi,


I seem to be getting ridiculously high CPU usage from "Interface Builder Cocoa Touch Tool", no online fixes seem to work so far, is anyone else experiencing this issue? It's literally making it unusable.


Thanks,

ND

It doesn't work for me because I don't have systemItem="trash" in my MainStoryboard


Problem not fixed...

I still have the same problem in Xcode 9.1

I was having this same problem, also using Xcode 9.1. I had a couple flexibleSpace barButtonItems in a toolBar. When I commented those out the problem went away.

Same problem here, Xcode 9.1 (9B55). Apple please fix this! Xcode becomes unresponsive and I cannot develop apps 😟

That's consistent with what I'm having problems with also. I first hit this trying to change a button image on a toolbar to the system camera icon. I thought I might be working with a corrupted project, but I just found that I can easily recreate this problem with a brand new project.


  1. add a toolbar
  2. drag the toolbar to bottom of the screen.
  3. Interestingly enough if you select the 'bar button item' and change the 'system item' to camera it will work, but do NOT do this yet.
  4. Add a second 'bar button item' to the toolbar.
  5. Select the original 'bar button item' and change the 'system item' to camera. 'Interface builder cocoa toach tool' spike CPU to 99%.

The link to stackoverflow did contain a solution that worked for me! Changing 'translatesAutoresizingMaskIntoConstraints' in the storyboard text fixes the problem for my toolbar.

This makes it a bit better for me, I don't have to force quit every hour atleast. It's so irritating when you can't build apps at the pace you used to before and it's affecting my productivity like crazy. I dread opening Xcode 9. It's absolutely hilarious that Apple would allow a product to be released with huge memory leaks, when we take so much care of them in our apps.
