UIHostingController presented modally as sheet breaks navigation bar back button safe area insets when iOS device is rotated

I have a SwiftUI View containing a basic NavigationStack structure. I host this in a UIHostingController and display modally as a sheet in UIKit using UIViewController.present().

Problem: When I rotate my iOS device to landscape from portrait, the navigation bar's back button extends past the safe area into the left corner of the device. Then, rotating back to portrait the back button is pushed further towards the center - not matching the intended position. (see images below).

Is there an API call I am missing to handle this rotation case? Thanks!

Code Example

SwiftUI view - ContentView.swift

import SwiftUI

struct ContentView: View {   
    var body: some View {
        NavigationStack {
            Form {
                NavigationLink {
                    Form {
                        Text("Hello")
                    }
                    .navigationTitle("Filter")
                    .navigationBarTitleDisplayMode(.inline)
                } label: {
                    Text("Filter")
                }
            }
            .navigationTitle("Filter")
            .navigationBarTitleDisplayMode(.inline)
        }
    }
}

Main UIKit ViewController - ViewController.swift

import UIKit
import SwiftUI

class ViewController: UIViewController {
    let swiftUIView = ContentView()
    var hostingController: UIHostingController<ContentView>?

    override func viewDidLoad() {
        super.viewDidLoad()
        hostingController = UIHostingController(rootView: swiftUIView)
        guard let hostingController else { return }

        hostingController.modalPresentationStyle = .formSheet

        // Immediately present modally
        DispatchQueue.main.async {
            self.present(hostingController, animated: true)
        }
    }
}

More Detail

The issue only seems to appear for sheet modal presentation including these UIModalPresentationStyle:

• .formSheet
• .pageSheet
• .popover

The issue does not appear in an app with SwiftUI app lifecycle or when using UIKit and adding the hosting controller as a child view controller. This specifically happens when presenting modally and when the view gets rendered as a sheet.

I tried various combinations of UIHostingController.sizingOptions and UIHostingController.safeAreaRegions, but never found something that fixed the issue.

To Build and Reproduce

1. Make a new Xcode project > iOS > App > Storyboard UI
2. Add file ContentView.swift with contents above.
3. Replace contents of existing file ViewController.swift with contents above.
4. Set minimum deployment target to iOS 18
5. Build and deploy to device running iOS 18.
6. Hold device in portrait.
7. Rotate device to landscape - observe back button extends past safe area.
8. Rotate device to portrait - observe back button is shifted too far towards the center.

Device & Builds Specs

• iOS 18.6.2 - minimum deployment of 18.0
• Devices Observed:
  • iPhone 12 Pro Max
  • iPhone 16 Pro Max
• Xcode 26
