I tried out the Xcode 10.2 beta a few days ago to check out Swift 5. I used it on my macOS 10.14.2 boot drive and my 10.14.4 beta SSD, and it seemed fine both times. A few days ago, Xcode stopped working; the Swift CLI tool I was working on, and a new project, crash before they even get to main
:
dyld: Library not loaded: /usr/lib/swift/libswiftSwiftOnoneSupport.dylib

Last time, my laptop was in the middle of a 10.14.3 install, but it still persists even though the install is finished.
I saw a suggested thread, and "SWIFT_FORCE_STATIC_LINK_STDLIB=YES
" didn't seem to help (or I put it in wrong).
