The filter() method of SequenceType does not take an NSPredicate as an argument, but a closure, e.g.

let filteredTableData = sortedLocations.filter {
    $0.name.localizedCaseInsensitiveContainsString(searchText)
}

The closure is called for each array element (here using the shorthand argument $0) and returns true or false to indicate if the element is to be included in the filtered result or not.

You can use an NSPredicate to filter an NSArray, that would look like

let filtered = someNSArray.filteredArrayUsingPredicate(predicate)

but there is no reason to use this if you have a Swift array.
