BannerView doesn't adjust after orientation from landscape to portrait in iOS

I am using the SwiftUI example  SwiftUI Demo BannerView  and rather than giving a fixed width, I read the width from GeometryReader. After orienting to landscape the banner view redraws nicely with the updated AdSize width, however the redrawing back to portrait from landscape causes the banner view to pour out of the screen boundaries. The orientation change from portrait(the start) to landscape works, but the orientation change from landscape to portrait doesn't work (the banner view pours out of screen). 

The updated BannerContentView is given below.

struct BannerContentView : View {

let navigationTitle : String

// [START add_banner_to_view]

var body : some View {

GeometryReader { geometry in

VStack {

Spacer ()

HStack {

Spacer ()

var adSize = currentOrientationAnchoredAdaptiveBanner(width: geometry. size . width * 0.90 )

BannerViewContainer (adSize)

                        . frame ( width : adSize. size . width , height : adSize. size . height )

Spacer ()

                }

            }

            . navigationTitle ( navigationTitle )

        }

    }

}

When I debug the adSize, the width values seem to be consistent between orientation changes (between orientations, width values are consistent). Somehow, the portrait drawing of the BannerView after landscape is problematic.

Is there a fixed for this error? What would you suggest? Thank you.

Hi,

I've raised this concern to the wider team and will get back to you once I receive any updates on it. Meanwhile, your patience is highly appreciated.

Hi,

We received an update from the wider team that GeometryReader is not the most reliable API for handling orientation changes in SwiftUI. Instead, it's recommended to use UIKit notifications or the sizeClass environment variable (e.g., @Environment(\.horizontalSizeClass) var horizontalSizeClass ) to respond to size change events.

I hope this helps! Let me know if you have any other questions.
