ios – SwiftUI animate background colour change when a situation is met

I am attempting to alter the background colour of the Textual content part, each time a given situation is met, on this instance, when numberOfTaps = 3, which I will do by having the situation contained in the .background property name

What I am attempting to do is to alter the background with an animation, nothing too fancy, simply one thing like .easeInOut may work; how can I try this?

import SwiftUI

struct ContentView: View {
    @State personal var numberOfTaps = 0
    
    var physique: some View {
        VStack {
            Button("Up") {
                numberOfTaps += 1
            }
            
            Textual content("(numberOfTaps)")
                .padding()
                .background(numberOfTaps == 3 ? Colour.blue : Colour.inexperienced)
            
            Button("Down") {
                numberOfTaps -= 1
            }
        }
    }
}

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

Here is a pattern of the present UI:
