Hi,
I was notified about quarantine files but I don't know why?
ITMS-91109: Invalid package contents - The package contains one or more files with the com.apple.quarantine extended file attribute
The mentioned file is to project logo as PNG image. The PNG file is located here:
MyApp.app/Contents/Resources
Who did notify ? Xcode ? AppStoreConnect ?
I don't know if it is the same problem, but I often had issue when importing png file in resources. The cause was the presence of "detritus".
The solution was to clear attributes with the following command in Terminal:
xattr -c theFile.png
