Swift easy manufacturing unit design sample

Easy manufacturing unit implementation utilizing switch-case

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

class ColorFactory {

    enum Type {
        case textual content
        case background
    }

    func create(_ model: Type) -> UIColor {
        swap model {
        case .textual content:
            return .black
        case .background:
            return .white
        }
    }
}


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

This may be actually helpful, particularly if it involves a sophisticated object initialization course of. You may as well outline a protocol and return numerous occasion varieties that implement the required interface utilizing a swap case block. 🚦

protocol Surroundings {
    var identifier: String { get }
}

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

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

class EnvironmentFactory {

    enum EnvType {
        case dev
        case dwell
    }

    func create(_ sort: EnvType) -> Surroundings {
        swap sort {
        case .dev:
            return DevEnvironment()
        case .dwell:
            return LiveEnvironment()
        }
    }
}

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

So, a number of issues to recollect concerning the easy manufacturing unit design sample:

+ it helps unfastened coupling by separating init & utilization logic 🤔
+ it is only a wrapper to encapsulate issues that may change usually 🤷‍♂️
+ easy manufacturing unit might be applied in Swift utilizing an enum and a switch-case
+ use a protocol in case you are planning to return completely different objects (POP 🎉)
+ hold it easy 🏭

This sample separates the creation from the precise utilization and strikes the duty to a selected position, so if one thing adjustments you solely have to change the manufacturing unit. You possibly can go away all of your exams and all the pieces else fully untouched. Highly effective and easy! 💪
