ios – Caching 2 separate person arrays on totally different desk view controllers utilizing person defaults

I am creating an app that has a procuring listing and a to-do listing on 2 totally different desk view controllers. I am new to caching and I am probably not proud of how the mannequin I’ve created seems to be. Additionally, it appears to save lots of the information for the procuring listing and never the to-do listing. It saves so effectively that even after deleting an merchandise, it reappears when terminating and reopening the app. The procuring listing shows 2 labels and a favorite button. The to-do listing is only one label. Does anybody have any recommendation?

Right here is the code within the cache mannequin I created:

import Basis

// Mannequin used to cache information within the desk view

struct ShopItemCache {
    static let shopItemKey = "store.merchandise.key"
    static let toDoKey = "todo.merchandise.key"
    static func setItems(objects: [ShopItem]) {
        let listing = ShopItems(objects: objects)
        if let information = attempt? JSONEncoder().encode(listing),
           let json = String(information: information, encoding: .utf8) {
            print("json (json)")
            UserDefaults.normal.set(json, forKey: shopItemKey)
            UserDefaults.normal.synchronize()
        }
    }
    static func setToDoItems(toDoItems: [ToDoItem]) {
            let listing = ToDoItems(toDoItems: toDoItems)
            if let information = attempt? JSONEncoder().encode(listing),
               let json = String(information: information, encoding: .utf8) {
                print("json (json)")
                UserDefaults.normal.set(json, forKey: toDoKey)
                UserDefaults.normal.synchronize()
            }
    }
    static func removeItem(idx: Int) {
        var objects = getItems()
        objects.take away(at: idx)
        UserDefaults.normal.set(objects, forKey: shopItemKey)
        UserDefaults.normal.synchronize()
    }

    static func getItems() -> [ShopItem] {
        guard let json = UserDefaults.normal.string(forKey: shopItemKey) else {
            print("json is lacking")
            return []
        }
        guard let information = json.information(utilizing: .utf8) else {
            print("information is lacking")
            return []
        }
        if let listing = attempt? JSONDecoder().decode(ShopItems.self, from: information) {
            return listing.objects
            
        } else {
            return []
        }
    }
    static func removeToDoItem(idx: Int) {
        var objects = getToDoItems()
        objects.take away(at: idx)
        UserDefaults.normal.set(objects, forKey: toDoKey)
        UserDefaults.normal.synchronize()
    }

    static func getToDoItems() -> [ToDoItem] {
        guard let json = UserDefaults.normal.string(forKey: shopItemKey) else {
            print("To-Do json is lacking")
            return []
        }
        guard let information = json.information(utilizing: .utf8) else {
            print("information is lacking")
            return []
        }
        if let listing = attempt? JSONDecoder().decode(ToDoItems.self, from: information) {
            return listing.toDoItems
        } else {
            return []
        }
    }
