The list of possible objects that can work as an activity in a `UIActivityViewController` is undocumented.

Steps to Reproduce:
- Look in the documentation for `UIActivityViewController`

Expected Results:
- There should be some sort of list or explanation what kind of objects can be shared as activities.

Actual Results:
- There is nothing like that


This is especially problematic as there seems to be much more than just an image, a string or plain data supported here. E.g. providing a `UIPrintPageRenderer` works. This is a duplicate of rdar://31147307
