Some users experience this kind of crash:
NSInternalInconsistencyException:Use of the class INVocabulary requires the entitlement com.apple.developer.siri.
Make sure you have enabled the Siri capability in your Xcode project.
During app startup, calling the following code causes a crash：
INVocabulary *vocabulary = [INVocabulary sharedVocabulary];
But our project definitely has siri configured to be available.
Now that we can't figure it out, is it a bug in the system？
