So trying my app in iOS17 destroyed FocusStates in my app, it has no issues in iOS16.

The situation is:

I have a "Create New Item" view, where the user can fill in the following information of an Item: Title, Amount, Note

I have these properties in the view:

@FocusState private var titleIsFocused: Bool
@FocusState private var amountIsFocused: Bool
@FocusState private var noteIsFocused: Bool

And using these Textfields:

TextField("title", text: $title)
.focused($titleIsFocused)

TextField("amount", text: $amount)
.focused($amountIsFocused)
.keyboardType(.decimalPad)

TextField("note", text: $note)
.focused($noteIsFocused)

When the view appears: I have a onAppear that sets:

titleIsFocused = true

I have the following ToolbarItemGroup in my toolbar:

ToolbarItemGroup(placement: .keyboard) {
  Button {
    if titleIsFocused {
    amountIsFocused = true
    }
    if amountIsFocused {
    noteIsFocused = true
    }
    if noteIsFocused {
    noteIsFocused = false
    }
  } label: {
    Text(noteIsFocused ? "Done" : "Next")
  }
}

The issue is:

In iOS16: the focus goes correctly from title to amount, from amount to note, and from note to closing the keyboard via the keyboard toolbar buttons.

In iOS17: nothing happens when I press the keyboard toolbar buttons. Also this does not work via normal buttons.

Weird thing is, this works:

Setting a .onSubmit{} on the TextField..

TextField("title", text: $title)
.focused($titleIsFocused)
.onSubmit { amountIsFocused = true }

However, a textfield with a '.keyboardType(.decimalPad)' has no Return/Submit button, and since the Textfield for amount is a decimalPad, it will not work nicely In my situation.

Question

Is something drastically changed from iOS16 to iOS17 how this should work, or is this just a bug in Beta1?

Doesn't work in WatchOS either, tried everything I can think of. Plain project with nothing but a TextField and an .onAppear{} modifier with a .main.asyncAfter{} with 1 second delay changing the focus state does not do anything. Focus always prints nil/false... how does this even slip by QA, idk.

Tried changing focus between two views both listening to Digital Crown change on a tap of a button. Doesn't work. Button action doesn't allow to change @FocusState value programmatically. Tap on a view changes @FocusState without problems.

Does this solve the issue? It works on my app.

import SwiftUI

struct FieldView: View {

    enum Field: Hashable {
        case amountField
        case descriptionField
        case categoryField
    }
    
    @FocusState private var focusedField: Field?

    @State var description = ""

    var body: some View {
        TextField("Description" ,text: $description)
            .focused($focusedField, equals: .descriptionField)
            .keyboardType(.default)
            .onAppear() {
                focusedField = .descriptionField
            }
            .onSubmit {
                focusedField = .categoryField
            }
            .submitLabel(.next)
        }
    }
}
