Swift easy manufacturing facility design sample

Easy manufacturing facility implementation utilizing switch-case

The aim of this sample is to encapsulate one thing that may usually differ. Think about a colour palette for an utility. You may need to alter the colours in response to the most recent behavior of the designer each day. I’d be actually inconvenient when you needed to search & substitute each single occasion of the colour code by hand. So let’s make a easy manufacturing facility in Swift that may return colours based mostly on a given fashion. 🎩

class ColorFactory {

    enum Fashion {
        case textual content
        case background
    }

    func create(_ fashion: Fashion) -> UIColor {
        change fashion {
        case .textual content:
            return .black
        case .background:
            return .white
        }
    }
}


let manufacturing facility = ColorFactory()
let textColor = manufacturing facility.create(.textual content)
let backgroundColor = manufacturing facility.create(.background)

This may be actually helpful, particularly if it involves a sophisticated object initialization course of. It’s also possible to outline a protocol and return numerous occasion sorts that implement the required interface utilizing a change case block. 🚦

protocol Setting {
    var identifier: String { get }
}

class DevEnvironment: Setting {
    var identifier: String { return "dev" }
}

class LiveEnvironment: Setting {
    var identifier: String { return "dwell" }
}

class EnvironmentFactory {

    enum EnvType {
        case dev
        case dwell
    }

    func create(_ kind: EnvType) -> Setting {
        change kind {
        case .dev:
            return DevEnvironment()
        case .dwell:
            return LiveEnvironment()
        }
    }
}

let manufacturing facility = EnvironmentFactory()
let dev = manufacturing facility.create(.dev)
print(dev.identifier)

So, just a few issues to recollect concerning the easy manufacturing facility design sample:

+ it helps free coupling by separating init & utilization logic 🤔
+ it is only a wrapper to encapsulate issues that may change usually 🤷‍♂️
+ easy manufacturing facility could be carried out in Swift utilizing an enum and a switch-case
+ use a protocol if you're planning to return totally different objects (POP 🎉)
+ maintain it easy 🏭

This sample separates the creation from the precise utilization and strikes the accountability to a particular function, so if one thing modifications you solely have to change the manufacturing facility. You may go away all of your assessments and all the things else fully untouched. Highly effective and easy! 💪
