Summary:
An hdiutil command I’d been running in a unit test to create HFS+ volumes doesn’t work for APFS. I gave these arguments: create -fs APFS -format UDRW -srcFolder <folder> -volname <name> -attach -plist <dmg name>

Steps to Reproduce:
1. Call hdiutil create -fs APFS -format UDRW -srcFolder <folder> -volname <name> -attach -plist <dmg name>

Expected Results:
A DMG gets created with the contents of <folder>

Actual Results:
It returns nonzero, and gives this stdout/stderr output:
