Now that @Observable macro has been out a little bit, what's the latest thinking on this? 🤔
How would one apply @MainActor to the ViewModel of the following code? Currently, doing so gives the "Call to main actor-isolated initializer 'init()' in a synchronous nonisolated context" error on the @State line in the TestApp struct.
import SwiftUI
@main
struct TestApp: App {
@State private var vm = ViewModel()
var body: some Scene {
WindowGroup {
ContentView()
.environment(vm)
}
}
}
@Observable
@MainActor
class ViewModel {
var showDetails: Bool = false
}
struct ContentView: View {
@Environment(ViewModel.self) var vm
var body: some View {
@Bindable var vm = vm
VStack {
DetailsButton(showDetails: $vm.showDetails)
if vm.showDetails {
Text("This is my message!")
}
}
}
}
struct DetailsButton: View {
@Binding var showDetails: Bool
var body: some View {
Button("\(showDetails ? "Hide" : "Show") Details") {
showDetails.toggle()
}
}
}
