Abstract Factory design pattern

In Simple: Factory of Factories

• EconomicCarFactory: Produces economic car variants.
• LuxuryCarFactory: Produces luxury car variants.
• Abstract Factory (e.g., CarProducer) decides which factory to use. shall we use economic car factory or luxury car factory and best on that will car.

Step-by-Step Code

1. Define the Car Protocol:
   This protocol will represent the properties and methods that each car will implement.

protocol Car {  
    var name: String { get }  
    func drive() -> String  
}

2. Implement Concrete Car Classes:
We will create specific implementations for both Economy and Luxury cars.

class EconomyCar1: Car {  
    var name: String { return "Economy Car 1" }  
    func drive() -> String { return "Driving an Economy Car 1" }  
}  

class EconomyCar2: Car {  
    var name: String { return "Economy Car 2" }  
    func drive() -> String { return "Driving an Economy Car 2" }  
}  

class LuxuryCar1: Car {  
    var name: String { return "Luxury Car 1" }  
    func drive() -> String { return "Driving a Luxury Car 1" }  
}  

class LuxuryCar2: Car {  
    var name: String { return "Luxury Car 2" }  
    func drive() -> String { return "Driving a Luxury Car 2" }  
}
