ios – Handle JSON File – Struct or Class?

I needed to ask a query about my doubt.

I am presently implementing my code for decoding a JSON file utilizing two buildings for the info mannequin and one FriendsManager class for knowledge administration

In your opinion is that this method or ought to I work with structs as a substitute of utilizing a class?

I am new to decoding JSON recordsdata and needed to ensure I used to be writing my code the appropriate approach

non-public let JSONFriendFileName = "Pals"

class FriendsManager: ObservableObject {

    var friendsList: [FriendsList] = []
    
    init() {
        let decoder = JSONDecoder()
        decoder.keyDecodingStrategy = .convertFromSnakeCase
        decode(fileName: JSONFriendFileName, decoder: decoder)
    }
    
     func decode(fileName: String, decoder: JSONDecoder) {
        
        guard let url = Bundle.essential.url(forResource: JSONFriendFileName, withExtension: "json") else {
            print("Non esiste alcun file denominato (JSONFriendFileName + ".json") in questo progetto")
            return
        }

        do {
            let knowledge = strive Information(contentsOf: url)
            let objects = strive decoder.decode(Pals.self, from: knowledge)

            friendsList = objects.friendsList

        } catch {
            print(error.localizedDescription)
        }
    }
}

struct Pals: Codable {
    var friendsList: [FriendsList]
}

struct FriendsList: Codable, Identifiable {
    let title: String
    let timestamp: Int?
    let contact_info: String?
    
    let id = UUID()
    
    enum CodingKeys: String, CodingKey {
        case title, timestamp, contact_info
    }
}

Information utilization

import SwiftUI

struct FriendsView: View {
    
    @StateObject non-public var friendsManager = FriendsManager()
    
    var physique: some View {
        NavigationView {
            Listing {
                ForEach(friendsManager.friendsList) { pals in
                    Textual content(pals.title)
                }
            }
            .navigationTitle("Pals")
        }
    }
}
