Current Behavior

TouchEffect does not work on iOS when app is built in Release. This is a regression in 9.1.0 and possibly due to AOT improvements.

Expected Behavior

TouchEffect should work and fire events/execute commands when attached to a view.

Steps To Reproduce

Create a new blank MAUI project
Add a TouchEffect to any control
Build the app in Release configuration

Link to public reproduction project repository

AotSample.zip

Environment

- .NET MAUI CommunityToolkit: 9.1.0
- OS: iOS 17.5
- .NET MAUI: 8.0.91 SR9.1 (latest)

Anything else?

Works in 9.0.3. Android works in both Debug and Release.

@brminnick Added reproduction project. I also get a persistent startup crash when debugging on iOS (Android is unaffected):

System.TypeLoadException: Could not set up parent class, due to: Invalid generic instantiation assembly:/Users/dev/Library/Developer/CoreSimulator/Devices/F766998B-9560-4192-90C8-DEC128E8E6D9/data/Containers/Bundle/Application/C4DE1219-9F4A-4D31-9354-A887F27BD4BF/AotSample.app/Microsoft.Maui.dll type:ViewHandler`2 member:(null)

I've tried the following steps mentioned here with no luck:

Update .NET 8 SDK to latest
Update MAUI workloads via dotnet workload update
Drop bin and obj
Clear local NuGet package cache

Rolling back to 9.0.3 everything works fine.
