MAUI iOS Publish to AppStore: Rejected because of BrowserEngineKit in use

[fabEps]

Description

I'm currently not able anymore to publish my (two different) MAUI Apps to the Apple App Store, since it gets rejected:

Hello,
We noticed one or more issues with a recent delivery for the following app:
...
Please correct the following issues and upload a new binary to App Store Connect.
ITMS-91017: Invalid SDK usage - The following frameworks aren’t permitted for apps using an alternative web browser engine: [BrowserEngineKit].

I installed the new .NET 8 SDK 8.0.402 update and the new workloads on our Mac Mini Buildserver, to support Xcode 16: https://github.com/xamarin/xamarin-macios/releases/tag/dotnet-8.0.1xx-xcode16.0-8303.

In the xcrun command from the build log, I can see the forbidden framework as weak_framework: -weak_framework BrowserEngineKit (see complete logoutput).

I tried to uninstall several NuGets (AppCenter, Firebase Cloud Messaging, InAppBilling), without success.

There are also some other guys encountering this problem: https://stackoverflow.com/questions/79030828/maui-ios-publish-fails-net8-0-browserenginekit

My App uses the WebView control - I created a custom one, but it derives from Microsoft.Maui.Controls.WebView which PlatformView is MauiWKWebView (WKWebView) and this should be fine, yes?

Of course, this happens when I have an app release coming up.. So is there a workaround?

Steps to Reproduce

1. Create new MAUI iOS App
2. Use a simple WebView to display a website inside the app
3. Build it on a mac with Xcode 16 and .NET 8 SDK 8.0.402
4. Try to upload to TestFlight

workaround: xamarin/xamarin-macios#21324 (comment)

[drasticactions]

Yeah, this is an underlying SDK issue, which should be resolved when xamarin/xamarin-macios#21337 lands. And the workaround for unlinking BrowserEngineKit (xamarin/xamarin-macios#21324 (comment)) should be fine for now.
