Just updated to Mac OS X Catalina (10.15) and Xcode 11.1, and some of my storyboards have gone red. All graphics appear to be there but, everything is RED. VERY red (as you can see below).
They still publish OK and this isn't a problem on Xcode 11.0 on a OS X Mojave (10.14.6) on my MacBook Pro?
Anyone? Thx

Obviously a change in storyboard previews in Xcode. Seems like it's no longer acceptable to show "simulated size: freeform" greater than iPhone screen height. Changing it to "simulated size: fixed" in Size Inspector solves the issue, and you can now scroll from within the reduced size window in storyboards view...
A change for the better? Let's see what happens...
