[iOS] [MAUI] System.Exception: 'No class inheriting from a valid Application Delegate found...'

[jp-weber]

Current behavior

I am currently unable to use Hot restart to deploy and start an iOS app that uses MAUI embedding.

System.Exception: 'No class inheriting from a valid Application Delegate found in /var/mobile/Containers/Data/Application/D75C8C78-C2D2-4942-B1CE-000D0DBFA821/Documents/MauiEmbedding.Mobile.content/MauiEmbedding.Mobile.dll'

Expected behavior

The app should deploy and launch like on Android.

How to reproduce it (as minimally and precisely as possible)

1. Download sample app: https://github.com/unoplatform/uno.extensions/tree/main/samples/MauiEmbedding
2. Start the VS project and debug on iOS device.
3. Start app on device
4. crash
