[Bug]: iOS Rich Media (Images) not working

[bnoffer]

What happened?

We are planning on switching from our custom Push Backend to OneSignal and one of the most important features for us is the possibility to send Images with our notifications. Sadly using SDKs 4.3.0 and 4.3.1 we are unable to do so for iOS, Android is working perfect. I triple checked the Setup Guide and iOS Troubleshooting steps and can not find any errors. I even cross-checked with my previous NotificationExtension, which is working fine. The images used work with our custom solution, but not with OneSignal.

Steps to reproduce?

1. Followed the Xamarin Quick Setup Steps
2. Created a Push Notification for Test Subscription inkl. Media Image Url
3. Check if image is shown on device

What did you expect to happen?

Image should be shown on iOS and Android.

OneSignal Xamarin SDK version

Release 4.3.1

Which platform(s) are affected?

• iOS
• Android

UPDATE
I continued testing and on the device console you can see that the Extension is triggered and fails with this event:

error: Failed to load AOT module 'OneSignal.iOS.Binding' while running in aot-only mode: compiled against GC , while the current runtime uses GC sgen.

I found a temporary solution:

I had the issue that Debugging on Device did not work for me for a while now and I basically fully cleared the Project and removed the App from my device and then I got a deployment failure:

DuplicateIdentifier: Found bundle at /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.VJI4gJ/extracted/App.iOS.app/Frameworks/Xamarin.framework with the same identifier (xamarin.ios.xamarin-framework) as bundle at /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.VJI4gJ/extracted/App.iOS.app/Frameworks/Xamarin-debug.framework

I googled for this and found xamarin/xamarin-macios#6920

Using the workaround mentioned in the following comment solved the issue for me: xamarin/xamarin-macios#6920 (comment) for Debugging on Device and in Release mode.

Since this is only a workaround, and I don't know yet if it is a Xamarin.iOS issue or caused by the Nuget, I will leave this issue open.

thanks @bnoffer for the update. I will continue trying to reproduce what you are seeing and will let you know what I come up with!
