Unfortunately, dealing with an array of strings is not as
straightforward as it might be.  If they are actually NSStrings, then
they're immutable.  KVC will try to change their value in situ, not
replace the object, and this obviously won't work...

See for example,

If you can replace your strings with dictionaries, life will be
easier...
