Since upgrading to XCode12.4 on two different MacBooks both running MacOS 10.15.6 I have issues opening Storyboard / Xib files.
Just to be clear this doesn't occur for a specific project - this happens for *any* project I open and for *any* storyboard / xib file within that project.
There is a long delay before the file opens and when it does I see.
1) The UIComponents in blue outline rather than the details.
2) The Error Message : An Internal Error Occurred Editing functionality may be limited
From my log.txt
=================================

ASSERTION:
=================================
Failed to update scene '01J-lp-oVM' with IBUIViewAutolayoutGuide (x1), UIView (x1), and UIViewController (x1).
Exception name: IBPlatformToolFailureException
Exception reason: The tool closed the connection

I've cleaned derived data / restarted my machine etc - all to no avail.
All I can do at this stage is reinstall XCode 12.4 unless anyone can make any suggestions?
