Ok, yep tried that and a couple others linked to from that thread and none of them worked.
This one:
LD_VERIFY_BITCODE = NO
And this one:
LD_RUNTIME_SEARCH_PATHS = /usr/lib/swift $executable_path/Frameworks @loader_path/Frameworks
Neither of them did the trick. Someone also mentioned just adding a new, blank Swift file, but that doesn't work either.

Same issue here. Previews crash on 16.0 beta 6 and 16.1 beta 1. Enabling "Editor -> Canvas -> Use Legacy Previews Execution" causes previews to start working again.
