Answer 1

Open Runner in Xcode then Go to Targets > Build Phases > Run Script: Add the following

xattr -cr ~/Library/Developer/Xcode/DerivedData || echo Clear

Then build the project.

The real issue is hidden in the xCode build logs.

The real error:

Finder information, or similar detritus not allowed

This means that there are some metadata attributes in one of your image files that xcode doesn't like.

To fix this, you can run the command listed in this answer to remove the metadata from your project's images:

find . -type f -name '*.png' -exec xattr -c {} \;

Or for all images:

  find . -type f -name '*.jpeg' -exec xattr -c {} \;
  find . -type f -name '*.jpg' -exec xattr -c {} \;
  find . -type f -name '*.png' -exec xattr -c {} \;
  find . -type f -name '*.json' -exec xattr -c {} \;
