How to filter NSArray in Swift?

Question

self.filteredUserData = self.userData.filter({( listing: NSDictionary) -> Bool in
        let stringMatch = listing["name"].rangeOfString(searchText)
        return stringMatch != nil
})

I was going to do something like above, but I realized 'NSArray' does not have a member named 'filter' and not a Swift Array. How can I filter NSArrays in Swift?

lol this is not an objective-c question. completely different syntax. — User, Sep 21 '14 at 02:51
You're not listening. Your question is not a _language_ question. It's a Cocoa / Foundation question (that's what NSArray is). You need to be language-agnostic if you want to work with Cocoa methods. The "translation" from that answer to yours is trivial; a machine could do it. — matt, Sep 21 '14 at 03:17

Here's what I ended up doing:

let resultPredicate = NSPredicate(format: "name contains[c] %@", searchText)
self.filteredUserData = self.userData.filteredArrayUsingPredicate(resultPredicate)

Objective-C version:

NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:@"name contains[c] %@", searchText];
self.filteredUserData = [self.userData filteredArrayUsingPredicate:resultPredicate];

So you did the second thing that I suggested. So how is this different from what I said? – matt Sep 21 '14 at 02:50

Well I actually wrote the code to show how different the syntax is. – User Sep 21 '14 at 02:51
