i changed that build system to Legacy Build system in File->Project settings . but it diden't work yet
this project made with xcode9 and i develope it with xcode 10 now
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.
