        Is there a way to remove the zillions of "CoreUI: RunTimeThemeRefForBundleIdentifierAndName() couldn't find Assets.car in bundle with identifier:" log records without adding an Assets.xcasset to every single framework, plugin, bundle in an application?

         

        These zillions of log records can cripple the performance of an application.

         

        Is this a bug in Catalina (still in b9)?

          I'm seeing this in 10.15 Beta (19A573a), so hopefully it's a bug they'll fix.

            Running my project with XCode 10.3 does nothing to solve this problem. I still get errors like:

             

            2019-10-22 16:39:44.764172-0600 Appname[10316:215611] [Nib Loading] Unknown class NSBoxCustom in Interface Builder file at path ...

            and

            2019-10-22 16:39:44.778901-0600 Appname[10316:215611] [framework] CoreUI: RunTimeThemeRefForBundleIdentifierAndName() couldn't find Assets.car in bundle with identifier: 'com.Appname'

             

            So it looks like the problem is Catalina, not XCode.

              Upgrading to Catalina 10.05.1 solves some problems. Foe example the error reported by the original poster:

               

              "CoreUI: RunTimeThemeRefForBundleIdentifierAndName() couldn't find Assets.car in bundle with identifier:"

               

              but XCode 11.1 still logs the following spurious errors:
