How to show data from app to Today Extension Swift

I have a app with data stored in core data but I also need to pass that data to my today extension. I was trying to do it with core data but it doesn't work. Maybe I would have to user userdefaults to pass the data from the app to the today extension.

Any help will be greatly appreciated.

Solution

I think target only missing.

Try like this

Add today extension target membership for .xcodeModalId

Step: Click on your model file, and select both targets under 'Target Membership' on right-hand panel
