Beta SDK is currently in the production phase and will be released soon. We are working diligently to finalize it and make it available for you to use.
Unless you need special use cases, Netmera handles all UIApplicationDelegate methods related to remote notifications, so you do not need to implement them in your App Delegate class.
However, if your application has use cases that require a custom implementation on remote notification delegate methods, you can freely implement them and perform your specific logic inside these delegate methods.
SDK provides [Netmera recentPushObject]/Netmera.recentPushObject() method which returns the object representation of the remote notification payload. You can use this method to access the NetmeraPushObject instance corresponding to the remote notification inside your UIApplicationDelegate methods.
