Question

How to completely delete entity description in Core Data Model editor in Xcode 4.4.1? The user interface has only the "Add Object" button.

Answer 1

• Select the object you want to delete.
• Press the backspace key.

Answer 2

I have a crash when trying to remove Entity by highlighting and pressing the Backspace key.

.xcodeproj in my case was to open .xcodeproj instead of .xcworkspace only for this operation, and Entity was successfully deleted.

Answer 3

In case of failure while trying to delete it. Try this:

1. right click .xcdatamodel file .xcdatamodel
2. click "show in search"
3. right click and "show package contents"
4. open the "content" file in XML format and delete the object that you no longer need.
