Swift manufacturing facility technique design sample

Manufacturing facility technique is only a non-static technique

Let’s face it, this sample is only a technique often backed by easy protocols & lessons. Begin with a very easy instance: think about a category that may create a base URL in your service endpoint. Let’s name it service manufacturing facility. 😅

class ServiceFactory {
    func createProductionUrl() -> URL {
        return URL(string: "https://localhost/")!
    }
}
let manufacturing facility = ServiceFactory()
manufacturing facility.createProductionUrl()

You may assume, that hey, this isn’t even near a manufacturing facility technique sample, however watch for it… let’s make issues a bit of bit sophisticated by making a protocol for the service class and a protocol for returning the URL as effectively. Now we are able to implement our base manufacturing URL protocol as a separate class and return that particular occasion from a manufacturing service manufacturing facility class. Simply test the code you’ll get it:

protocol ServiceFactory {
    func create() -> Service
}

protocol Service {
    var url: URL { get }
}

class ProductionService: Service {
    var url: URL { return URL(string: "https://localhost/")! }
}

class ProductionServiceFactory: ServiceFactory {
    func create() -> Service {
        return ProductionService()
    }
}

let manufacturing facility = ProductionServiceFactory()
let request = manufacturing facility.create()

Why did we separated all of the logic into two lessons and protocols? Please consider me decoupling is an efficient factor. To any extent further you can simply write a mocked service with a dummy URL to mess around with. Clearly that’d want an identical manufacturing facility class.

These mock situations would additionally implement the service protocols so you can add new varieties in a comparatively painless method with out altering the unique codebase. The manufacturing facility technique solves one particular drawback of a easy manufacturing facility sample. If the listing – contained in the switch-case – turns into too lengthy, sustaining new objects shall be hell with only one manufacturing facility. Manufacturing facility technique solves this by introducing a number of manufacturing facility objects.
