Obyekt qachon yaratiladi?

iOS'da ob'ekt quyidagi holatlarda yaratiladi:

1. Sinf yoki tuzilmaning boshlanishi (yangi nusxa yaratish).

class MyClass {
    init() {
        // Boshlash kodi
    }
}

let myObject = MyClass() // MyClass ob'ektini yaratish

struct MyStruct {
    var value: Int

    init(value: Int) {
        self.value = value
    }
}

let myStructInstance = MyStruct(value: 10) // MyStruct tuzilmasining nusxasi

2. Ma'lumotlarni deserializatsiya qilish (masalan, JSON dan).

struct User: Codable {
    let name: String
    let age: Int
}

let jsonData = """
{
    "name": "Alice",
    "age": 30
}
""".data(using: .utf8)!

let decoder = JSONDecoder()
if let user = try? decoder.decode(User.self, from: jsonData) {
    // user - yaratilgan User ob'ekti
}

3. Fabrik metodlaridan foydalanish, ular yangi nusxa qaytaradi.

class MyFactory {
    static func createObject() -> MyClass {
        return MyClass() // Fabrik metod yangi ob'ekt yaratadi va qaytaradi
    }
}

let anotherObject = MyFactory.createObject()

4. Core Data ob'ektlarini NSEntityDescription.insertNewObject(forEntityName:into:) yordamida yaratish.

import CoreData

// Faraz qilamizki, kontekst mavjud NSManagedObjectContext
if let entity = NSEntityDescription.entity(forEntityName: "MyEntity", in: context) {
    let myCoreDataObject = NSManagedObject(entity: entity, insertInto: context) // Core Data ob'ekti yaratish
    // Ob'ektning xususiyatlarini sozlash
}

5. Interface Builder (XIB/Storyboard) orqali, ob'ektlar (masalan, ViewController) aniqlanadi.

import UIKit

let storyboard = UIStoryboard(name: "Main", bundle: nil)
if let viewController = storyboard.instantiateViewController(withIdentifier: "MyViewController") as? MyViewController {
    // viewController - yaratilgan MyViewController ob'ekti
}

Yaratilish vaqti init chaqirilishi yoki yangi nusxa yaratadigan metod chaqirilishi bilan aniqlanadi.
