I believed that I would be good to have a summarized comparability between all of the manufacturing unit patterns, so right here it’s every little thing that it is best to find out about them. Developing them is comparatively simple, on this instance I’ll use some UIColor magic written within the Swift programming language to indicate you the fundamentals. 🧙‍♂️

Static manufacturing unit

• no separate manufacturing unit class
  • named static technique to initialize objects
  • can have cache & can return subtypes

extension UIColor {
    static var major: UIColor { return .black }
    static var secondary: UIColor { return .white }
}

let major = UIColor.major
let secondary = UIColor.secondary

Easy manufacturing unit

• one manufacturing unit class
• change case objects within it
• encapsulates various code
• if record is just too large use manufacturing unit technique as an alternative

class ColorFactory {
    enum Fashion {
        case major
        case secondary
    }

    func create(_ fashion: Fashion) {
        change fashion
        case .major:
            return .black
        case .secondary:
            return .white
    }
}
let manufacturing unit = ColorFactory()
let major = manufacturing unit.create(.major)
let secondary = manufacturing unit.create(.secondary)

Manufacturing unit technique

• a number of (decoupled) manufacturing unit lessons
• per-instance manufacturing unit technique
• create a easy protocol for manufacturing unit

protocol ColorFactory {
    func create() -> UIColor
}

class PrimaryColorFactory: ColorFactory {
    func create() -> UIColor {
        return .black
    }
}

class SecondaryColorFactory: ColorFactory {
    func create() -> UIColor {
        return .white
    }
}

let primaryColorFactory = PrimaryColorFactory()
let secondaryColorFactory = SecondaryColorFactory()
let major = primaryColorFactory.create()
let secondary = secondaryColorFactory.create()

Summary manufacturing unit

• combines easy manufacturing unit with manufacturing unit technique
  • has a worldwide impact on the entire app

protocol ColorFactory {
    func create() -> UIColor
}

class PrimaryColorFactory: ColorFactory {
    func create() -> UIColor {
        return .black
    }
}

class SecondaryColorFactory: ColorFactory {
    func create() -> UIColor {
        return .white
    }
}


class AppColorFactory: ColorFactory {

    enum Theme {
        case darkish
        case mild
    }

    func create(_ theme: Theme) -> UIColor {
        change theme {
        case .darkish:
            return PrimaryColorFactory().create()
        case .mild:
            return SecondaryColorFactory().create()
        }
    }
}

let manufacturing unit = AppColorFactory()
let primaryColor = manufacturing unit.create(.darkish)
let secondaryColor = manufacturing unit.create(.mild)

So these are all of the manufacturing unit patterns utilizing sensible actual world examples written in Swift. I hope my sequence of articles will aid you to achieve a greater understanding. 👍
