swift - Search Bar with UISearchControllerDelegate and/or UISearchBarDelegate and/or UISearchController -

i newbie in swift , want implement search bar seems there not tutorials on how right new protocols apple introduced.

i have named tuple data in (name, category, details , on, , of type string)

i have read documentation still inexperienced , don't know how implement new magic.

my question how can make search bar , search bar display controller (the former deprecated) work tuple?

sample code is:

var mydata = namedtuple(   category: "lorem ipsum",                            name: "dolor",                            details: "some info on subject."                        )      objects.append(mydata)  // , on...  var objects = [mydata]()
