I am working on a mac app which includes a helper app (for auto launch on system startup) and a finder sync extension. All three apps have crashed at different times due to this error:Dyld Error Message: Symbol not found: _$SBOWVReferenced from: {path to app} Expected in: /usr/lib/swift/libswiftCore.dylibin {path to app}I have found exceptionally little useful information about this online, and it is very frustrating. Please help!

Hi everyone (ideally Eskimo, if you're reading this),I'm developing an application which includes a Finder Sync Extension, and extremely often the extension simply doesn't appear when launching the app. The extension is visible and enabled in System Preferences, but it is nowhere to be found in Finder. I recently uncovered this error message buried in system.log:`Mar 8 00:49:43 My-Retina com.apple.xpc.launchd[1] (com.myDomain.myApp.FinderSyncExtension.9AA0B404-2C28-49EC-B94C-DADA6501380E[1550]): Caller wanted oneshot behavior for pre-existing instance: caller = com.apple.appki`I found someone else who posted about the same thing:https://help.nextcloud.com/t/mac-finder-extension-not-working/38363Can someone help me understand what this error message means and how to address it?Thanks a lot,Jeremy
