Goals

What do you want to achieve?

I am unable to set the userId property in the current version of the SDK, however both the native iOS and Android SDK's allow this ability. Could this functionality please be exposed to the Unity SDK. I see there is functionality implemented in the IOSWrapper.cs to achieve this, but I can't seem to access it directly.

Code Samples & Details

Please provide a code sample, as well as any additional details, to help us track down the issue. If you can provide a link to a test project that allows us to reproduce the issue, this helps us immensely in both the speed and quality of the fix.

Note: Remember to format your code for readability:

// Current iOS Functionality
AppEvents.userId = "foo"

// Desired C# Functionality
FB.SetUserId("foo");
