Xcode 7.0.1 crashes when setting NSSplitView 'Content Compression Resistance Priority' in Interface Builder

I'm getting a pretty consistent crash in interface builder(EXC_BAD_ACCESS) that occurs when trying to change colors or fonts.

I'm getting many crashes in Interface Builder (Xcode 7.0.1) when changing stackview properties (see below). When I'm using XCode 7.1 beta 3 Interface Builder displays "An internal error occured. Editing functionality may be limited" and it becomes very very slow.

I'm blocked for the dev of my App 😠

Have you found any workaround for this issue?

I'm still blocked, Interface Builder is unusable. I have reproduced the same issue with a new project that contains only a storyboard with 1 view controller, with a table view, 6 UILabel and several UIStackViews.

I have filled a bug (23060936) but not feedback at this time.

Same here. Getting constant crashes since XCode 7, seen in XCode 7.0.1 and then today with the update to the official release of XCode 7.1. (Also was running OS 10.11 El Capitan, and still happening with todays update to 10.11.1). Constant crashes when using Interface Builder. Setting colors, fonts, font styles, or adjusting the sizes of controls, etc. I have to continually hit CMD-S to save every time I make a change in a storyboard because it crashes so consistently. Never seen a bug this bad in XCode or anything like this from Apple. I've submitted bug reports, and will keep doing so for each crash. They need to escalate this bug and put out a fix.

I have installed Xcode 7.1 and I still have the issue but Xcode doesn't crash anymore but Interface Builder displays the following error message "An internal error occured. Editing functionality may be limited".

The message is right because I'm not able to update my storybooard 😠

No, I haven't found a fix yet. I just hit CMD-S repeatedly after every single change I make. Still crashes repeatedly though. Anybody try the XCode 7.2 beta yet and see if the bug is still there?

I'm downloading XCode 7.2beta and I will try it.

With Xcode 7.1 it's doesn't crash but I get an error "An internal error occured. Editing functionality may be limited".

Since yesterday I have more issues with XCode, ibtool fails (error code 255) with one of my storyboards and then my whole project becomes unusable (very slow). I'm also not able to fix this error in Ibtools, a real nightmare.
