Searchbar filtering issue

Question

Im new to the swift, I am trying to filter name from an array using the search bar in console am getting what I entered in the search bar but filtering with predicate im not

Answer 1

The most efficient way to filter custom classes is to use the same type for the data source array and the filtered array

var caseListOfBooker = [CaseDetails]()
var filteredBooker = [CaseDetails]()

Add a property isFiltering which is set to true when the search text is not empty

var isFiltering = false

and delete searchString and filteredString

var searchString:String=""
var filteredString = [String]()

In updateSearchResults filter the data source array (with native Swift functions), set isFiltering accordingly and reload the table view

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
    print("searchText \(searchText)")
    updateSearchResults(searchText: searchText)
}

func updateSearchResults(searchText: String) {
    if searchText.isEmpty {
        filteredBooker.removeAll()
        isFiltering = false
    } else {
        filteredBooker = caseListOfBooker.filter{$0.person_of_interest.range(of: searchText, options: .caseInsensitive) != nil }
        isFiltering = true
    }
    tableview.reloadData()
}

In the table view data source methods display the data depending on isFiltering

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return isFiltering ? filteredBooker.count : caseListOfBooker.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableview.dequeueReusableCell(withIdentifier: "POIProfileDetailsCell", for: indexPath) as! POIProfileDetailsCell
    let booker = isFiltering ? filteredBooker[indexPath.row] : caseListOfBooker[indexPath.row]
    cell.poiName.text = booker.person_of_interest
}
