Conditionally Text in SwiftUI depending on Array value

I want make placeholder custom style so i try to use the method of Mojtaba Hosseini in SwiftUI. How to change the placeholder color of the TextField?

if text.isEmpty {
            Text("Placeholder")
                .foregroundColor(.red)
        }

but in my case, I use a foreach with a Array for make a list of Textfield and Display or not the Text for simulate the custom placeholder.

          ForEach(self.ListeEquip.indices, id: \.self) { item in
     ForEach(self.ListeJoueurs[item].indices, id: \.self){idx in
// if self.ListeJoueurs[O][O] work
        if self.ListeJoueurs[item][index].isEmpty {
                                    Text("Placeholder")
                                        .foregroundColor(.red)
                                }
    }
    }

How I can use dynamic conditional with a foreach ?
