var body: some View {
TextField("Text", text: $viewModel.text) // Cannot find '$viewModel' in scope

I also had that problem, this is the solution: add
@Bindable var viewModel = viewModel
in your view’s body, even though I don’t think it is elegant.
@Observable
final class View1Model {
var text: String = ""
struct View1: View {
@State var viewModel = View1Model()
var body: some View {
View2()
.environment(viewModel)
struct View2: View {
@Environment(View1Model.self) var viewModel
var body: some View {
// use @Bindable to get the binding
@Bindable var viewModel = viewModel
TextField("Text", text: $viewModel.text)
This code has good performance. But it is not cleaner than @EnvironmentObject
struct View2: View {
@Environment(View1Model.self) var viewModel
var body: some View {
TextField("Text", text: Binding(get: {
viewModel.text
}, set: { newValue in
viewModel.text = newValue
Using @Bindable could be better as you would have to create this new Binding for every property you need to access.
We are still in beta you must remember: things could change.
The most elegant solution I've found is to extract the view and pass the model to a @Bindable property.
@Observable
final class View1Model {
var text: String = ""
struct View1: View {
@State var viewModel = View1Model()
var body: some View {
View2()
.environment(viewModel)
struct View2: View {
@Environment(View1Model.self) var viewModel
var body: some View {
View3(viewModel: viewModel)
struct View3: View {
@Bindable var viewModel: ViewModel
var body: some View {
TextField("Text", text: $viewModel.text)
