Hello,

xcode7 beta4 crashed whenever I open the storyboard with an internal assertion error on UILabel (see below). Wondering if anybody has seen similar issue and can shed some light on this issue:

Hi,

I am seeing this error in Xcode 6.4 Each time it seems to be choosing a different UILabel, but mine for height. not width.

This could be caused by the presence of old runtimes as mentioned in the Release Notes:

Xcode processes may quit unexpectedly if older iOS Simulator runtimes (Xcode 6.x) are present on disk

To see if that's the case (or to rule it out as a cause), delete all (old) runtimes from /Library/Developer/CoreSimulator/Profiles/Runtimes.
