Can you name the main creational design patterns?

The main creational design patterns are patterns that help create objects by hiding their creation details and simplifying the process. They include:

• Singleton — ensures only one instance of a class exists and provides a global access point.
• Factory Method — defines an interface for creating an object but allows subclasses to change the type of objects created.
• Abstract Factory — provides an interface for creating families of related objects without specifying their concrete classes.
• Builder — separates the construction of a complex object from its representation, allowing different representations.
• Prototype — creates new objects by copying existing ones.

Example of Singleton in Swift:

class Singleton {
    static let shared = Singleton()
    private init() { }

    func doSomething() {
        print("Singleton works")
    }
}

Singleton.shared.doSomething()
