I have an array of dictionaries. I would like to filter that array by seeing if the @”name” field of each dictionary contains a given string.
The catch is that I would like to make my filtering insensitive to case and diacritics.
If the array contained only strings I could easily use an NSPredicate. However, it doesn’t, and I don’t see a way that NSPredicate can accomodate this situation.
If I only cared about case-insensitivity, I could loop through all the items and compare the lowercased filter string to the lowercased name. But I don’t know of a similar trick for diacritics.
Is there a good solution to this somewhere?
Check the top answer on this question:

You should be able to use that code to get rid of the diacritics and then do a case insensitive compare or search.
