@available(iOS 14.0, *)
public struct EnumMenuPicker<T: Hashable & CaseIterable, V: View>: View {
    
    @Binding var selected: T
    var title: String? = nil
    let mapping: (T) -> V

                Button(action: {
                    selected = item
                }, label: {
                    view(for: item)

    @ViewBuilder func view(for item: T) -> some View {
        if selected == item {
            HStack {
                Image(systemSymbol: .checkmark)
                self.mapping(item)
            }
        } else {
            self.mapping(item)
        }
    }
}

Could you please add an example code snippet on how to make use of this class?

I have following enum in my project.

enum VideoQuality: CaseIterable {
    case noChange
    case low
    case medium
    case high
    
    var name: String {
        switch self {
        case .noChange:
            return "Same as source"
        case .low:
            return "Low"
        case .high:
            return "High"
        case .medium:
            return "Medium"
        }
    }
    
    var value: String {
        switch self {
        case .noChange:
            return AVAssetExportPresetPassthrough
        case .low:
            return AVAssetExportPresetLowQuality
        case .high:
            return AVAssetExportPresetHighestQuality
        case .medium:
            return AVAssetExportPresetMediumQuality
        }
    }
}

Can you please provide a code snippet on how to use this enum into your class?
