Easiest way to search from UITableView using UISearchBar in minimum line of code in UIViewController

1. Directly drag and drop the HSSearchable.swift into your xcode project.

2. Most recommanded: install via cocoapods (How to use cocoapods)

   pod 'HSSearchable'
   

import HSSearchable

//Suppose this is your datamodel
struct UserDM {
  var name: String
  var city: String
 }

1. extend your class or Structure using the SearchableData delegate

   extension UserDM: SearchableData {
    var searchValue: String{
      return self.name + " " + self.city //this will search from the name and city both
   
      //return self.name //this will search from the name only
    }
   }
   

2. Create a variable of 'SearchableWrapper' in the viewController as property

   var usersData = SearchableWrapper()
   var users: [UserDM] { //use this array as you are using array for your tableview controller
      return self.usersData.dataArray as! [UserDM]
   }
   

3. Set the searchbar delegate and Searching callback

   override func viewDidLoad() {
      super.viewDidLoad()
      self.searchbar.delegate = self.usersData
      self.usersData.searchingCallBack = { isSearching, searchText in
          print("searching Text:= \(searchText)")
          self.tableView.reloadData()
      }
      self.loadDummyData()
   }
   

4. Set the local array or load data from the server usign API|Webservice call

    func loadDummyData(){
          //This is just an example data
          let user1 = UserDM(name: "Hitendra Solanki", city: "Ahmedabad")
          let user2 = UserDM(name: "Justina Flores", city: "Arizona")
          let user3 = UserDM(name: "Lisa Minick", city: "Casper")
          let user4 = UserDM(name: "Moises Patrick", city: "Reno")
          let user5 = UserDM(name: "Martha Fisher", city: "Tacoma")
          let user6 = UserDM(name: "Martha McDaniel", city: "Irvine")
          let array : Array<UserDM = [
              user1,
              user2,
              user3,
              user4,
              user5,
              user6
          ]
          //In most of the cases, this data will come from the server side
          self.usersData.serverArray = array;
          self.tableView.reloadData()
    }
   

5. Optional Setps: HSSearchable also supports the optional customDelegate, using this you can handle default UISearchabarDelegate methods in your own viewControllers.

      self.usersData.customDelegate = self //implement UISearchbarDelegate in your class
