Search bar not working in IOS app swift 3

I would like to implement a search bar into my swift application, which I have successfully done so, but for some reason when I go to search for anything nothing shows up in my table view any help would be greatly appreciated.

Here is my controller



import UIKit
import AudioToolbox


class TableController: UITableViewController, UISearchBarDelegate{


var PhoneArray = [String]()

var filtered:[String] = []

var searchActive = false



@IBOutlet weak var searchBar: UISearchBar!




override func viewDidLoad() {
super.viewDidLoad()
tableView.dataSource = self
tableView.delegate = self
searchBar.delegate = self
searchBar.returnKeyType = UIReturnKeyType.done
getData("http://phonedir.mydomain.com/getPhoneList")
}


override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if(searchActive)
{
print("Search")
return filtered.count

}
return PhoneArray.count
}


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

if searchBar.text == nil || searchBar.text == "" {

searchActive = false
print("search not active")
view.endEditing(true)

tableView.reloadData()

} else {

searchActive = true
print("search is active")
filtered = PhoneArray.filter({$0 == searchBar.text})

tableView.reloadData()
}
}

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)

//let phone = PhoneData[indexPath.row]
//let name = indexPath.row
if(searchActive)
{
let array = filtered[indexPath.row]
//print("search Active")
cell.textLabel?.text = array.replacingOccurrences(of: " ", with: "").replacingOccurrences(of: "[", with: " ").replacingOccurrences(of: "]", with: " ").replacingOccurrences(of: "&", with: "*")
cell.textLabel?.numberOfLines=0
cell.textLabel?.sizeToFit()

cell.textLabel?.lineBreakMode = NSLineBreakMode.byWordWrapping

cell.textLabel?.textColor = UIColor.white

if (indexPath.row % 2 == 0)
{
cell.backgroundColor = UIColor(red: 22/255, green: 160/255, blue: 133/255, alpha: 1.0)
}
else
{
cell.backgroundColor = UIColor(red: 44/255, green: 62/255, blue: 80/255, alpha: 1.0)
}
}
else
{
let array = PhoneArray[indexPath.row]
//print("search not Active")

cell.textLabel?.text = array.replacingOccurrences(of: " ", with: "").replacingOccurrences(of: "[", with: " ").replacingOccurrences(of: "]", with: " ").replacingOccurrences(of: "&", with: "*")
cell.textLabel?.numberOfLines=0
cell.textLabel?.sizeToFit()

cell.textLabel?.lineBreakMode = NSLineBreakMode.byWordWrapping

cell.textLabel?.textColor = UIColor.white

if (indexPath.row % 2 == 0)
{
cell.backgroundColor = UIColor(red: 22/255, green: 160/255, blue: 133/255, alpha: 1.0)
}
else
{
cell.backgroundColor = UIColor(red: 44/255, green: 62/255, blue: 80/255, alpha: 1.0)
}
}

return cell
}



func getData(_ link:String)
{
let url = URL(string: link)!
let request = URLRequest(url: url, cachePolicy: .reloadIgnoringCacheData, timeoutInterval: 20)
URLSession.shared.dataTask(with: request) { (data, response, error) in
if error != nil {
print(error!)
let alertController = UIAlertController(title: "No Connection", message:
"Phone directory connection could not be established", preferredStyle: UIAlertControllerStyle.alert)
alertController.addAction(UIAlertAction(title: "Dismiss", style: UIAlertActionStyle.default,handler: nil))

self.present(alertController, animated: true, completion: nil)

return
}

do {
if let jsonData = try JSONSerialization.jsonObject(with:data!, options: []) as? [[String:Any]] {
//print(jsonData)
for item in jsonData {

if let phone_first = item["EMP_FIRST_NAME"] as? String
{
if let phone_last = item["EMP_LAST_NAME"] as? String
{
if let phone_ext = item["PHONE_EXT"] as? String
{



self.PhoneArray.append(" [" + phone_first + "]" + " [" + phone_last + "]" + "&" + phone_ext + "&")
}
}
}

DispatchQueue.main.async {
self.tableView.reloadData()
}
}
}
} catch let error as NSError {
print(error)
}
}.resume()

//print(self.PhoneArray)
}

}


Here is what it looks like when I load it normally without the search



Without Search

here is what it looks like when I do search, as you can my table view doesn't display anything



With Search

Answer Source

The problem lies here:

filtered = PhoneArray.filter({$0 == searchBar.text})

You should check if the string contains the search text

filtered = PhoneArray.filter({$0.contains(searchBar.text)})
