Swift easy manufacturing facility design sample

Easy manufacturing facility implementation utilizing switch-case

The purpose of this sample is to encapsulate one thing that may typically range. Think about a colour palette for an utility. You may need to vary the colours in keeping with the most recent behavior of the designer every day. I would be actually inconvenient when you needed to search & change 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 model. 🎩

class ColorFactory {

    enum Fashion {
        case textual content
        case background
    }

    func create(_ model: Fashion) -> UIColor {
        change model {
        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 an advanced object initialization course of. You too can outline a protocol and return varied 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, a couple of 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 typically 🤷‍♂️
• easy manufacturing facility may 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 🎉)
• preserve it easy 🏭

This sample separates the creation from the precise utilization and strikes the duty to a particular position, so if one thing adjustments you solely have to switch the manufacturing facility. You possibly can go away all of your assessments and every thing else utterly untouched. Highly effective and easy! 💪
