Trying to use xcode 10 to open my project's xib files for the first time, but get this error:
"An internal error occured. Editing functionality may be limited."
The xcode xib editor does come up but clearly is wrong. has blue outlines for views, and other oddities. This worked fine in older xcode versions. I have tried deleting the drived data folder and rebuilding. The xib's header versions are such:
document type="com.apple.InterfaceBuilder3.CocoaTouch.XIB" version="3.0" toolsVersion="6250"
any ideas? I have never used anything but xcode for my xib editing.
