Application getting crashed on setting the vocabulary for carName using Siri Kit - ios11

Question

I am trying to develop an application using SiriKit to get the car door lock status and set the same from Siri. I followed this blog https://www.appcoda.com/sirikit-introduction/ and did all the setup replacing the INStartWorkoutIntent with INGetCarLockStatusIntent.
But when i try to set the vocabulary for carName, the application is getting crashed with following exception,
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Illegal attempt to provide vocabulary of type INVocabularyStringTypeCarName by an app that does not handle any intents that could use that type of vocabulary'
The source code that i am using to set the vocabulary is,
INPreferences.requestSiriAuthorization { (status) in
}
INVocabulary.shared().setVocabularyStrings(["benz", "bmw", "audi"], of: .carName)
In AppDelegate, i have added the following method,
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: #escaping ([Any]?) -> Void) -> Bool {
guard let intent = userActivity.interaction?.intent as? INGetCarLockStatusIntent else {
print("AppDelegate: Start Workout Intent - FALSE")
return false
}
print("AppDelegate: Start Workout Intent - TRUE")
print(intent)
return true
}
Also created the extension for intent handler and implemented INSetCarLockStatusIntentHandling, INGetCarLockStatusIntentHandling protocols. I am getting this issue when i try to run it in iPhone 10.

Check, if in TARGETS of your project in Build Phases->Embed App Extensions added your Siri Extension. Maybe if you replace the INStartWorkoutIntent with INGetCarLockStatusIntent, old INStartWorkoutIntent remained there.
My crash fix this.

I was facing a similar issue. Make sure your extension's Deployment Target is set to appropriate iOS version. Creating an extension with the latest Xcode (at the moment 10.1) will set the Deployment Target to 12.1 and thus cause crash when run on iOS 10. So you should change it to your desired minimum.
