Search bar in UITableView for Realm objects

I have a table view populated by Realm Objects, and when i click on a cell, it takes me to another view that shows me more information about that Object. I want to add a search bar for this table view to check for the objects' "fullName" property. I know how to add a search bar for an array of strings, but I haven't found any tutorial or guidance on how to do it using Swift 2.0. Any help please?

EDIT: That's how i'm populating my tableview

var dataSource : Results<Patient>!

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    let identifier: String = "myCell"
    var cell = tableView.dequeueReusableCellWithIdentifier(identifier)

    if cell == nil {
        cell = UITableViewCell(style: .Subtitle, reuseIdentifier: identifier)
    }

    let currentPatientInfo = dataSource[indexPath.section]

    cell?.textLabel?.text = currentPatientInfo
    cell?.accessoryType = UITableViewCellAccessoryType.DetailDisclosureButton

    return cell!

}

I have the data in sections, not rows

EDIT: I added RealmSwiftSearchController to my project but occasionally i get this error when i click on a cell :

fatal error: unexpectedly found nil while unwrapping an Optional value

and it points to this code :

extension RealmSearchViewController {


 public override func tableView(tableView: UITableView, willSelectRowAtIndexPath indexPath: NSIndexPath) -> NSIndexPath? {

// The line below
    let object = self.fetchedResultsController.objectAtIndexPath(indexPath) as! Object
// Line ends
        self.resultsDelegate.searchViewController(self, willSelectObject: object, atIndexPath: indexPath)

        return indexPath
    }

There's an open-source component called RealmSearchViewController that should be able to take care of pretty much all of the boilerplate code necessary with setting up a searchable UITableView as well as interoperating it with Realm: https://github.com/bigfish24/ABFRealmSearchViewController

Additionally, there's a tutorial on how to implement it available on the Realm website: https://realm.io/news/building-an-ios-search-controller-in-swift/
