when running Xcode in 10.14 beta 3 (or 2) if I right click on a project product and then choose "Show in Finder" nothing is displayed; this happens with both Xcode beta 10 and Xcode version 9.4.1
Show in Finder from Xcode
This function s working here. Using Beta 3 on High Sierra.
Yes. It works fine in High Sierra but not Mojave
Finder is now blocking AppleEvents from all Applications that are not Sandboxed. Ironically this includes Apples own Applications like Xcode.
Hopefully this change it's not intentional or at least they need to whitelist System Apple Events...
