Swift manufacturing facility methodology design sample

Manufacturing facility methodology is only a non-static methodology

Let’s face it, this sample is only a methodology normally backed by easy protocols & courses. Begin with a very easy instance: think about a category that may create a base URL on 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 would possibly suppose, that hey, this isn’t even near a manufacturing facility methodology sample, however watch for it… let’s make issues a little bit bit sophisticated by making a protocol for the service class and a protocol for returning the URL as effectively. Now we will implement our base manufacturing URL protocol as a separate class and return that particular occasion from a manufacturing service manufacturing facility class. Simply verify 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 courses and protocols? Please imagine me decoupling is an effective factor. Any more you could possibly 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 could possibly add new varieties in a comparatively painless method with out altering the unique codebase. The manufacturing facility methodology solves one particular drawback of a easy manufacturing facility sample. If the record – contained in the switch-case – turns into too lengthy, sustaining new objects can be hell with only one manufacturing facility. Manufacturing facility methodology solves this by introducing a number of manufacturing facility objects.
