Comparing factory design patterns – The.Swift.Dev.

I believed that I might be good to have a summarized comparability between all of the manufacturing facility patterns, so right here it’s the whole lot that you need to find out about them. Establishing them is comparatively simple, on this instance I’ll use some UIColor magic written within the Swift programming language to indicate you the fundamentals. 🧙‍♂️

• no separate manufacturing facility 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

• one manufacturing facility class
• change case objects inside it
• encapsulates various code
• if listing is just too massive use manufacturing facility technique as an alternative

class ColorFactory 
    enum Model 
        case major
        case secondary
    

    func create(_ type: Model) 
        change type
        case .major:
            return .black
        case .secondary:
            return .white
    

let manufacturing facility = ColorFactory()
let major = manufacturing facility.create(.major)
let secondary = manufacturing facility.create(.secondary)

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

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()

• combines easy manufacturing facility with manufacturing facility technique
• has a world 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 gentle
    

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


let manufacturing facility = AppColorFactory()
let primaryColor = manufacturing facility.create(.darkish)
let secondaryColor = manufacturing facility.create(.gentle)

So these are all of the manufacturing facility patterns utilizing sensible actual world examples written in Swift. I hope my collection of articles will provide help to to realize a greater understanding. 👍
