joo | Simple class declaration function to write OO code | Reflection library

I am beginner in swift and Xcode 12, I am trying to implement core data correctly in my project after forgetting to check the option Core data when I have created the project , I manipulated my appDelegate.swift and also I had wrote few code lines about core data functions , but I still face problems with it like the error type 'NSManagedObject' has no member 'fetch' for example , I feel I have not implemented core data correctly

here my AppDelegate.swift after few manipulations :

I have this xml data

I want to remove duplicates in the list, but append elements in the list when there are no duplicates in the existing data but only in the extend() method, not in the append() method (because I will treat an added list in the append() method as one distinctive datum).

My new project is a small "puzzle" game where you enter a room and solve a puzzle inside, then when you go back to the level select section it opens up the next level.

I have thus far been using a single variable "lock" to count up once every time you beat a level and if the value of "lock" corresponds with the level number it would let you through.

Problem is that it seems when I use location.href it resets the "lock" variable.
