How correctly to write down current date in Core Data?
I did this
newUser.setValue(NSDate(), forKey: "date")
In the database itself, the following parameters are selected

After installing the application on an ios device, I make a couple of entries and pull out the .xcdatamodeld file, open it with the sqlitebrowser program and see the following
In the column, you can see not the date, but a set of numbers

Answer 1

CoreData is so more convenient to store the date, when you pull out the object, you should get the correct result.
What do you want to do with the file? What problem/problem are you solving?
