xcode 8.3 CompileStoryboard Internal error. UICGColor encodeWithCoder. Please file a bug at and attach ...

Was dancing with my voodoo drum for a few minutes after upgrading to xcode 8.3 today. One of my storyboards that have existed for last 3 years suddenly started to cause the compile error:

CompileStoryboard bLocNote/taxi/EditTariffStoryboard.storyboard

Was compiling fine just an hour ago on xcode 8.2.1! Ok, it tells something on not liking the UIColor, and log it mentions further says colors should be RGB or White space. I went by "binary search" removed everything from the storyboard except the table view -> build still fails. Only value catching the eye was "Tracking" color for the section view saying showing a black stripe with no color name, I have many of these assigned in other places though, guess it is still somehow different in this storyboard, so I reselected a "black" color for it:

And it compiled! Huraaay and back to programming!
