Keyboard toolbar breaks backside protected space after background on iOS 26

Listed here are the steps to breed the problem:

• iOS 26+ required

• create any enter that triggers opening keyboard

• add toolbar to keyboard (with any buttons)

• open keyboard (e.g. by focusing enter)

• shut keyboard

• background app (warnings are printed on this step)

• get again to foreground

• see that backside protected space is damaged (you’ll be able to add any view that’s certain to protected space)

Eradicating toolbar fixes the problem, btw.

The next warnings are printed:

-[RTIInputSystemClient remoteTextInputSessionWithID:performInputOperation:]  carry out enter operation requires a legitimate sessionID. inputModality = Keyboard, inputOperation = dismissAutoFillPanel, customInfoType = UIUserInteractionRemoteInputOperations

-[RTIInputSystemClient remoteTextInputSessionWithID:performInputOperation:]  carry out enter operation requires a legitimate sessionID. inputModality = Keyboard, inputOperation = dismissAutoFillPanel, customInfoType = UIUserInteractionRemoteInputOperations

Snapshotting a view (0x15b0a4800, UIKeyboardImpl) that’s not in a visual window requires afterScreenUpdates:YES.

Here’s a take a look at venture for demonstrating the problem:

import SwiftUI

struct ContentView: View {
    @State var choice: Int = 0
    @State var presentingModal = false

    var physique: some View {
        NavigationStack {
            VStack(spacing: 0) {
                TabView(choice: $choice) {
                    Group {
                        Button("Current") { self.presentingModal = true }
                            .tag(0)
                        Textual content("Second").tag(1)
                    }
                    .toolbar(.hidden, for: .tabBar)
                }

                HStack(spacing: 0) {
                    ForEach(0...1, id: .self) { tab in
                        Picture(systemName: "cloud.heavyrain.fill")
                        .padding(.vertical, 16)
                        .body(maxWidth: .infinity)
                        .contentShape(Rectangle())
                        .onTapGesture {
                            choice = tab
                        }
                    }
                }
                .padding(.horizontal, 16)
                .background(Colour.secondary)
            }
            .ignoresSafeArea(.keyboard)
            .navigationTitle("Title")
            .navigationBarTitleDisplayMode(.inline)
        }
        .sheet(isPresented: $presentingModal) {
            PresentedView()
        }
    }
}

struct PresentedView: View {
    @State var textual content = ""
    @FocusState var isInputActive: Bool

    var physique: some View {
        NavigationStack {
            VStack {
                TextField("", textual content: $textual content)
                    .targeted($isInputActive)
                    .padding()
                    .background(.secondary)

                Spacer()
            }
            .padding(.prime, 40)
            .padding(.horizontal, 20)
            .toolbar {
                ToolbarItemGroup(placement: .keyboard) {
                    Button("Shut") {
                        isInputActive = false
                    }
                }
            }
        }
    }
}
