Swift Ios Parse SearchBar Complication - ios

Question

I was recently following a tutorial which shows an early version of Swift being used to create a table of users from Parse with a search function. The following code has allowed me to display all users in a table as I would like, but does not update the table once search text has been put in the search bar. (There are two user arrays because I am relatively new to programming and was following two different tutorials to help make this table). Any help is greatly appreciated!!
var userArray: [String] = []
var userList:NSMutableArray = NSMutableArray()
#IBOutlet weak var searchBar: UISearchBar! = UISearchBar()
func loadUsers(name:String){
var findUsers:PFQuery = PFUser.query()
if !name.isEmpty {
findUsers.whereKey("name", containsString: name)
}
findUsers.findObjectsInBackgroundWithBlock{
(objects:[AnyObject]!, error:NSError!) -> Void in
self.userList = NSMutableArray(array: objects)
self.tableView.reloadData()
}
}
func searchBar(searchBar: UISearchBar, textDidChange searchText: String) {
loadUsers(searchText)
}
func searchBarCancelButtonClicked(searchBar: UISearchBar) {
loadUsers("")
}
override func viewDidLoad() {
super.viewDidLoad()
loadUsers("")
searchBar.delegate = self
self.navigationItem.hidesBackButton = true
var query = PFUser.query()
query.whereKey("username", notEqualTo: PFUser.currentUser().username)
var users = query.findObjects()
for user in users {
userArray.append(user["name"] as String)
println(userArray)
}
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Potentially incomplete method implementation.
// Return the number of sections.
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete method implementation.
// Return the number of rows in the section.
return userArray.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell:UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("cell") as UITableViewCell
if userArray.count >= 1 {
cell.textLabel?.text = userArray[indexPath.row]
}
return cell
}

You will have to create a new array which holds the data which hold's the results in the searchBar.
Besides, it's better to create a bool variable to handle what's the data showing in the screen (true for search results, false for loadUsers).
