mac-app-storequicklook

Why does the Xcode Symbols tool fail when submitting an application to the Mac App Store?

When I submit my application for the Mac App Store I get the following error:

The symbols tool failed, could not determine the executable path for the item path: "<DVTFilePath:0x2c242c1c0:'/var/folders/6j/ndqvj9rj68938svkmy7_d75c0000gn/T/XcodeDistPipeline.~~~gkLhyf/MyAppQuickLook.qlgenerator'>".

The error message then invites me to file a bug report at https://feedbackassistant.apple.com.

Is this necessary though? I've spotted a few things which make me wonder if the problem is mine.

  1. There has never been a problem previously. When submitting using older versions of Xcode, I never saw this error.
  2. The code for the Quicklook Generator hasn't changed. There are two warnings in the code - these being about casting to a smaller integer type (which is deliberate, but I include for completeness)
  3. The application also contains a Spotlight importer. This too contains no changed code, and it doesn't seem to be causing any problems. It also has the same warning about casting.
  4. I have a Copy Files build phase for both the QLGenerator (Quicklook) and the MDImporter (Spotlight), with a destination of Wrapper and the appropriate Subpath for both. Both are set to Code Sign on Copy.
  5. Looking in the General tab of the Project, I see that MyAppSpotlight.mdimporter is present, with Embed & Sign. MyAppQuicklook.qlgenerator is missing. If I attempt to add it directly here then it ends up the Copy Files phase as a plugin - in either event it doesn't work.
  6. I am running Xcode 13.3.1 (13E500a) on an M1 Mac mini.
  7. For what it's worth, all the code is written in Objective C - but it passes its tests (i.e. in testing the QLGenerator does what it is supposed to do)

Does this look like something that I can fix (any suggestions on how?) or do I in fact need to follow the invitation to file a bug report?

Solution

  • This is a known Xcode issue and should be fixed in Xcode 13.4:
