When a dictionary is copied, the objects it contains are not copied,

Returns the portion of the receiver not clipped by its superviews.

Make the header a subview of your datastream-view and put it into the

Simple, brute-force method: archive the dictionary, then unarchive it.
The result is a 1-line "deep copy".
Of course, that assumes that all the dictionary objects/keys support
