Advertising Identifier

IOS Native doesn't use any of this

class: ASIdentifierManager
selector: advertisingIdentifier
framework: AdSupport.framework

Please check if your XCode has AdSupport.framework  probably it was added by another plugin.

It can be also added by Unity if you will use NotificationServices class.

The IOS Native plugin use it for push notification but is disabled by default. To make sure the Push notification API is disabled:

1) Open Plugins Settings: Window -> IOS Native -> Edit Settings

2) Make sure that Push Notification API Is disabled
