Objective Sharpie fails with errors originating in the SDK's header files

Question

I am trying to bind an Objective-C library and I have successfully generated the binaries. However, when using Objective Sharpie, I get a list of errors that seem to be originating inside the iOS SDK. I launch the following command:

sharpie bind --output RealtimeSharp --namespace Realtime --sdk iphoneos9.0 ./Realtime/OrtcClient.h

and I get the following output:

Submitting usage data to Xamarin...
  Submitted - thank you for helping to improve Objective Sharpie!

Done. Exiting with error code 1.
error: Clang failed to parse input and exited with code 1

My list of SDKs (sharpie xcode -sdks):

sdk: iphoneos9.0          arch: arm64   armv7
sdk: macosx10.11          arch: x86_64  i386
sdk: watchos2.0           arch: 
sdk: watchsimulator2.0    arch:

My Objective Sharpie version is (sharpie --version):

2.1.6p 6e2f8ea 6e2f8ea5ac2f544c58938555a06ef21a4ecb032a 2015-03-17 17:39:55

And my Xamarin Studio's version is 5.9.7 (build 9).

I can generate binding successfully after adding -xobjective-c after the -c argument. Somethings like:

sharpie bind -output Binding -sdk iphoneos9.2 -scope build/Headers build/Headers/Example/Example.h -c -xobjective-c -Ibuild/Headers -arch arm64

My Sharpie version is 3.0.8.

Xamarin says it's an Objective Sharpie's bug, so they will be releasing a new version soon.
