UIViewController of Share Extension have a property:

    NSExtensionContext *extensionContext;

NSExtensionContext have a property:

    NSArray *inputItems;

Which have a 0-indexed object of NSExtensionItem class

Next, NSExtension Item have a property:

    NSArray *attachments;

Which is an array of objects of NSItemProvider class, and now it is time to go to read some documentation for NSItemProvider class
