Tested my app on an old iPhone 4 with the latest iOS Version for it.
Runs fine on other devices with iOS 8&9, but raises this exception on iOS 7.1.2
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIConcreteLocalNotification category]: unrecognized selector sent to instance 0x15df9cb0'
Commenting out line 45 and 75 in RCTPushNotificationManager.m fixed it for me since I don't need categories in my local push notifications.
45 //notification.category = [RCTConvert NSString:details[@"category"]];
75 //formattedLocalNotification[@"category"] = RCTNullIfNil(notification.category);
