Enum of structs in Swift

So I want to store color setup locally, but it would be better if I only save a String value. Then use this string to get the corresponding value. Below is my result:

So I want to store color setup locally, but it would be better if I only save a String value. Then use this string to get the corresponding value. Below is my result:

// MyColor.swift
class MyColor {
    private init() {}
    static let primary = Color("primary")
    static let onPrimary = Color("onPrimary")
    static let secondary = Color("secondary")
    static let onSecondary = Color("onSecondary")
}

struct ColorPair {
    let bg: Color
    let onBg: Color
}

enum ColorPairType: String {
    case primary = "primary"
    case secondary = "secondary"

    func value() -> ColorPair {
        switch self {
        case .primary:
            return ColorPair(bg: MyColor.primary, onBg: MyColor.onPrimary)
        case .secondary:
            return ColorPair(bg: MyColor.secondary, onBg: MyColor.onSecondary)
    }
}

// DemoView.swift

@State var currentColor: ColorPairType = .secondary

Text("hello")
    .foregroundColor(currentColor.value().onBg)

If you find this article useful, maybe you can buy my calculator for $0.99? It's a calculator that can change the layout of the keys. This way you can only keep the keys that are useful to you. -> App Store
