How to make non gray disabled button in swiftui

To create a non-gray disabled button in SwiftUI, you can use the ButtonStyle protocol to customize the appearance of your button, including its disabled state. Here's an example of how you can achieve this:

import SwiftUI

struct CustomButtonStyle: ButtonStyle {
    func makeBody(configuration: Configuration) -> some View {
        configuration.label
            .padding()
            .background(configuration.isPressed ? Color.blue : Color.green)
            .foregroundColor(.white)
            .cornerRadius(8)
            .opacity(configuration.isPressed ? 0.5 : 1.0)
            .overlay(
                RoundedRectangle(cornerRadius: 8)
                    .stroke(Color.blue, lineWidth: 2)
            )
            .opacity(configuration.isEnabled ? 1.0 : 0.5) // Adjust opacity for disabled state
    }
}

struct ContentView: View {
    @State private var isDisabled = true

    var body: some View {
        VStack {
            Button("Tap me") {
                print("Button tapped")
            }
            .buttonStyle(CustomButtonStyle())
            .disabled(isDisabled)

            Toggle("Disable Button", isOn: $isDisabled)
                .padding()
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

In this example, the CustomButtonStyle struct conforms to the ButtonStyle protocol and customizes the button's appearance. The opacity modifier is used to change the button's opacity when it is disabled, but you can customize other properties as well to achieve the desired look.
