Xcode apparently does not create the app’s dSYM file

Question

I am developing an iOS app. Sometimes when I execute the development version on a test device that is not connected to Xcode, the app crashes.
I later connect it to Xcode and display the device logs, and can see the crash log.

Unfortunately, my Xcode Version 12.5 (12E262) does not symbolicate my app. Apparently, Xcode does not find the required dSYM file, although I have set in Targets/Build Settings "Debug Information Format" to "DWARF with dSYM file".

I have read the docs „Adding Identifiable Symbol Names to a Crash Report“, particularly the section Locate a dSYM Using Spotlight. Accordingly:
In the „Binary Images:“ part of my crash report, my app is shown:

0x104c30000 - 0x104dd3fff ShopEasy arm64  <2f9607e3500937bdb7f84ad8f4c103d5> /var/containers/Bundle/Application/8CC841E3-385A-4779-97AF-1399E4D108F5/ShopEasy.app/ShopEasy

However, if I open var in the Finder, the folder containers is empty.

When I search in Terminal for the UUID using

mdfind "com_apple_xcode_dsym_uuids == 8CC841E3-385A-4779-97AF-1399E4D108F5"

it does not find anything.

Any help is welcome!

Answer 1

I am not sure if this is really the solution:
In Target / Build Settings, Debug Information Format was set to DWARF with dSYM File.
I reset it to DWARF only, and then set it again to DWARF with dSYM File.
Now my crash logs are symbolicated.
