Select the xcdatamodeld file in the project navigator, select the entity and press ⌥⌘3 – in Xcode 13 ⌥⌘4 – to show the Data Model Inspector.

If you created the class manually the Codegen popup must be set to Manual/None otherwise the class file is created implicitly.

In Xcode 11

1.Remove info list from Build Phases > Copy Bundle Resources

2.Remove Created Subclass from Build Phases > Compile Sources

Than Run if its not working use legacy build settings

From: File > Project Settings > build settings > legacy build settings
