Parse search in iOS 8 with Swift

I have been getting a lot of requests to show how to implement Parse search functionality uing Swift.Previously I had shown how to implement search : UISearchBar and UISearchBarDelegate if you haven’t checked that before I suggest you to take a look at it to get an overall idea.

Lets dive directly into code and I will explain what it does. Most of the code is boilerplate code for UITableViewController. The main function is to take the search text and implement the search functionality. In this case we would ideally want the search to be done on the server side and not client side hence we make use of the where key for containsString in the PFQuery class to perform search on server side and return the results.

import UIKit

class ParseSearchTableViewController: UITableViewController, UISearchBarDelegate {

    @IBOutlet weak var searchBar: UISearchBar!
    var searchActive : Bool = false
    var data:\[PFObject\]!
    var filtered:\[PFObject\]!
    override func viewDidLoad() {

        searchBar.delegate = self
        /\* Add some data \*/
//        for index in 1...10{
//            let obj = PFObject(className: "SearchText")
//            obj\["text"\] = "Text here \\(index)"
//        }

    override func didReceiveMemoryWarning() {
        // Dispose of any resources that can be recreated.

    func search(searchText: String? = nil){
        let query = PFQuery(className: "SearchText")
        if(searchText != nil){
            query.whereKey("text", containsString: searchText)
        query.findObjectsInBackgroundWithBlock { (results, error) -> Void in
   = results as? \[PFObject\]


    override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        if( != nil){
        return 0

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell
        let obj =\[indexPath.row\]
        cell.textLabel!.text = obj\["text"\] as? String
        return cell

    func searchBarTextDidBeginEditing(searchBar: UISearchBar) {
        searchActive = true;

    func searchBarTextDidEndEditing(searchBar: UISearchBar) {
        searchActive = false;

    func searchBarCancelButtonClicked(searchBar: UISearchBar) {
        searchActive = false;

    func searchBarSearchButtonClicked(searchBar: UISearchBar) {
        searchActive = false;

    func searchBar(searchBar: UISearchBar, textDidChange searchText: String) {
        search(searchText: searchText)

If the amount of data you are searching is small this approach might be ok, but this is not ideal for full text search. You can also take a look at this blog post for understanding how it can be done efficiently
