How to bind a #publish datamodel in SwiftUI? - swift

Question

Is there any way to bind a data model in swiftui?
I have coded like below and need to build a struct so that I can use it in multiple views but the problem is to know how to bind a #publish data model in swiftui?
var birds: [PlayerItem] = [PlayerItem(id: UUID(), playershow: false)]
var dogs: [PlayerItem] = [PlayerItem(id: UUID(), playershow: true)]
class Controller: ObservableObject {
#Published var bird = birds
#Published var dog = dogs
}
struct PlayerItem: Hashable {
var id = UUID()
var playerShow: Bool
}
struct ContentView: View {
#EnvironmentObject var control: Controller
var body: some View {
setButton(isOn: $Controller.bird)
}
}
struct setButton: View {
#Binding var isOn: [PlayerItem]
var body: some View {
Button(action: {
self.isOn[0].toggle()
}) {
Text(isOn[0] ? "Off" : "On")
}
}
}
I wrote the following code:
#Binding var isOn: [PlayerItem]
However, it complained the following:
Value of type 'EnvironmentObject<controller>.Wrapper' has no dynamic member 'isOn' using the key path from the root type 'Controller'

try the following code, it shows how to use #Binding and how you have to use playershow
class Controller: ObservableObject {
#Published var bird = [Playeritem(id: UUID(), playershow: false)]
#Published var dog = [Playeritem(id: UUID(), playershow: true)]
}
struct Playeritem: Hashable {
var id = UUID()
var playershow: Bool
}
struct ContentView: View {
#StateObject var control = Controller() // <-- for testing
var body: some View {
setButton(isOn: $control.bird) // <-- here control
}
}
struct setButton: View {
#Binding var isOn: [Playeritem]
var body: some View {
Button(action: {
self.isOn[0].playershow.toggle() // <-- here playershow
}) {
Text(isOn[0].playershow ? "Off" : "On") // <-- here playershow
}
}
}
