To pass a fill style like .fill.secondary as a parameter to a function in SwiftUI, you can define a function that accepts a ShapeStyle parameter. Here's an example of how you might do this:

import SwiftUI

struct ContentView: View {
    var body: some View {
        VStack {
            customShape(fillStyle: .fill.secondary)
        }
    }
    
    func customShape(fillStyle: ShapeStyle) -> some View {
        Circle()
            .fill(fillStyle)
            .frame(width: 100, height: 100)
    }
}

In this example, the customShape function takes a ShapeStyle parameter called fillStyle. When calling this function, you can pass .fill.secondary or any other fill style you want to use.
