You don't call the "save" function anywhere. You can call it, when you tapped on this image

struct SwiftUIView: View {
    var body: some View {
        HStack {
            Image("car1")
                .onTapGesture {
                    save()
                }
        }
    }
    
    func save(){
        UIImageWriteToSavedPhotosAlbum(UIImage(named: "car1")!, nil, nil, nil)
    }
}

Or create the button in HStack or VStack

struct SwiftUIView: View {
    var body: some View {
        HStack {
            Image("car1")
            Button("Save") {
                save()
            }
        }
    }
    
    func save(){
        UIImageWriteToSavedPhotosAlbum(UIImage(named: "car1")!, nil, nil, nil)
    }
}
