import SwiftUI

struct ContentView: View {
    
    // @Environment: A property wrapper that reads a value from a view’s environment.
    
    // Access the 'colorScheme' from the environment
    // The current 'colorScheme' used by the system.
    @Environment(\.colorScheme) var colorScheme
    
    var body: some View {
        Text("The current Color Scheme is \(colorScheme).").bold()
