If you're developing for iOS 10 and your app "silently" crashes (especially if it's an older app), the culprit could well be the increased privacy requirements in iOS 10. Namepaces such as HomeKit now require specific privacy-related keys to be in your info.plist (for instance, NSHomeKitUsageDescription). If you don't have them, the system automatically closes your application without an exception or Console.log message (if you run in the simulator, you may see a PRIVACY_VIOLATION notice in the stack trace).
