Not sure if this will help anyone - but make sure you have Find Implicit Dependencies checked off  Sometimes this can lead to your project  losing track  of where to look for certain things           Once you do this  I suggest then also cleaning your project and rebuilding

None of the bulk action solutions have worked for me  The extended attributes don t get removed  Each time this has happened for me it was a problem with one or more 3D models   dae  or a  png file  I have found that removing attributes  detritus  one file at a time works out to be faster in the end  I had to switch to the art scnassets directory in terminal   You can drag it from finder to terminal  For each suspect  new  file  I ran  quot xattr -lr filename ext quot  to see if it had extended attributes  If so  I ran  quot xattr -cr filename ext quot  to remove them  It has worked every time  but only by removing the attributes for each file  Then use Product - Clean Build Folder  and Build again  It has worked every time without fail

After i copied two  aiff files in a  scnassets group  this error occured  Deletion of the files and a  Clean Build Folder  solves the problem in my case

This is because Code signing no longer allows any file in an app bundle to have an extended attribute containing a resource fork or Finder info  To see which files are causing this error  go to  app folder  normally is like   Users XXXX Library Developer Xcode DerivedData MyProject-ckbzynxqjmstxigbdwwkcsozlego Build Products Debug-maccatalyst   mine is Catalyst project  In Terminal  cd  lt above path gt  xattr -lr    You will see some files has extended attribute    MyProject app Contents Resources shopping cart png  com apple lastuseddate PS  00000000  BE 31 D5 5E 00 00 00 00 D0 40 FE 39 00 00 00 00    1         9      Then go to your project folder or referenced folder for those files  remove extended attribute  cd  Users XXXX Work MyProject xattr -cr    After clean all referenced folders  go to Xcode and rebuild
