Unity 5.2.1f iOS Push notification Exception

[packedbox]

Hi i'm integrating parse in my Unity Project, Object creation works fine but I'm having some trouble with the push notification, the device never seem to register with the server on iOS.
using 5.2.1p3

Using ilcpp backend, Link.xml is located in the Asset's folder root.

ExecutionEngineException: Attempting to call method 'System.Reflection.MonoProperty::StaticGetterAdapterFrame' for which no ahead of time (AOT) code was generated.

This seems really strange. It would appear that this might be an IL2CPP bug. I'll see what I can figure out.

Bumping this! We're getting exactly the same exception being thrown. Unity 4.6.8, Xcode 7.0. Building with IL2CPP.

Update - iPad Air (iOS 7.0.4), iPhone 6 (9.0.2), 4S (9.0.2) and iPad 3 (9.0.2) all have the same issue. The 64-bit devices log to HockeyApp, the others do not but they all show the exception in Xcode logs.

Really hoping to get fixed for a game update due to crashes, hope you can find something @richardjrossiii , we'll look into it too. Thx.

Hey guys, just to give you an update -

The core issue is that unity does not export System.Runtime.Reflection.PropertyInfo for types compiled AOT using IL2CPP.

As a result, our code for dynamically determining whether the application was compiled using Unity 4 or 5 does not work (relevant LOC: https://github.com/ParsePlatform/Parse-SDK-dotNET/blob/master/Parse/PlatformHooks.Unity.cs#L1064-L1109).

As of right now, I'm not entirely sure of a solution that works to still support both Unity 4 and 5 without issue, however, I will keep you guys updated.

Hi Richards, thanks for your answer.
You might as well create two projects/dlls and code for Unity4 and Unity5
In my experience using a lot Reflection is often a source of trouble with Unity and it is only getting worse with IL2CPP.

Same Problem with Unity 5.2.2 and parse 1.6.1
I don't think any of your fix made to the 1.6.1

if I build the Dll from using the latest commits I manage to have this error instead :
KeyNotFoundException: The given key was not present in the dictionary.

AppIdentifier and TimeZone are null
I tried to fix it by adding tests to ForceSetIfDifferent
But I'm still not seeing any iOS installation on my Parse dashboard
