UITableView Search For Name In Object

I am trying to search through an array of objects that are retrieved from Parse to display the results in a UITableView. I tried using the same method that I used in one of my other apps, but in that case it was just searching through an array of strings.

This is my code at the moment:

func filterContentForSearchText(searchText: NSString) {
    let resultPredicate = NSPredicate(format: "SELF beginswith[cd] %@", searchText) //Use either contains or beginswith
    searchResults = DataManager.sharedInstance.rideArray.name.filteredArrayUsingPredicate(resultPredicate)
}

func searchDisplayController(controller: UISearchDisplayController!, shouldReloadTableForSearchString searchString: String!) -> Bool {
    self.filterContentForSearchText(searchString)
    return true
}

I understand why it doesn't work, but I can't figure out a solution to the problem. The property that I want to search for within the 'Ride' object is name.

Can anyone help me out? Thanks!

Assuming rideArray is an array of Parse objects that have a property name, the predicate should be

NSPredicate(format: "name beginswith[cd] %@", searchText)

And you filter the array with

rideArray.filteredArrayUsingPredicate(searchPredicate)
