SwiftUI: How to set background color by color name string

Question

I have var color: String = "blue". With that variable I want to set the background color of a Button. I tried .background(Color(color)), but that doesn't work. .background(Color.blue) or .background(Color(.blue)) work, but I want to use the String variable for it. How to do this?

You could compare the string which comes in and get the correct color from that. See the following example:

struct ContentView: View {
    
    var body: some View {
        Color(wordName: "red")
    }
}


extension Color {
    
    init?(wordName: String) {
        switch wordName {
        case "clear":       self = .clear
        case "black":       self = .black
        case "white":       self = .white
        case "gray":        self = .gray
        case "red":         self = .red
        case "green":       self = .green
        case "blue":        self = .blue
        case "orange":      self = .orange
        case "yellow":      self = .yellow
        case "pink":        self = .pink
        case "purple":      self = .purple
        case "primary":     self = .primary
        case "secondary":   self = .secondary
        default:            return nil
        }
    }
}
