값 유형을 할당 할 수 없습니다.

Question

셀을 클릭하면 url로 이동하는 tableView가 포함 된 신속한 응용 프로그램을 만들고 있습니다. 내가 tableview 내부 검색을 구현하지만 SearchBar 코드 내부에 두 개의 오류가 발생했습니다.

여기 내 코드입니다.

import Foundation 
import UIKit 

class ViewControllerAnalysis: UIViewController, UITableViewDelegate, UITableViewDataSource, UISearchBarDelegate { 

    @IBOutlet weak var searchBar: UISearchBar! 

    @IBOutlet weak var tableview: UITableView! 

    struct TableItem { 
     let url: String 
     let name: String 
     let symbol: String 
    } 

    let data = [ 
     TableItem(
      url: "https://www.zacks.com/stock/quote/AAPL?q=aapl?q=AAPL?q=AAPL", 
      name: "Apple Inc.", 
      symbol: "AAPL" 
     ), 
     TableItem(
      url: "https://www.zacks.com/stock/quote/GOOG?q=goog?q=GOOG?q=GOOG", 
      name: "Google Inc.", 
      symbol: "GOOG" 
     ), 
     TableItem(
      url: "https://www.zacks.com/stock/quote/FB?q=fb?q=FB?q=FB", 
      name: "Facebook Inc.", 
      symbol: "FB" 
     ), 
     TableItem(
      url: "https://www.zacks.com/stock/quote/AMZN?q=amzn?q=AMZN?q=AMZN", 
      name: "Amazon", 
      symbol: "AMZN" 
     ) 
    ] 

    let cellIdentifier = "Cell" 

    var filteredData: [String]! 

    override func viewDidLoad() { 
     super.viewDidLoad() 

     var filteredData = data 

     self.tableview.dataSource = self 
     self.tableview.delegate = self 
    } 

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

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
     return self.data.count 
    } 

    func numberOfSections(in tableView: UITableView) -> Int { 
     return 1 
    } 

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
     let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as! StockTableViewCell 

     let item = data[indexPath.row]cell.stockNameLabel?.text = item.name 
     cell.stockSymbolLabel?.text = item.symbol 

     return cell 
    } 



    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { 
     let item = data[indexPath.row] 
     let url = URL(string: item.url) 
     if #available(iOS 10.0, *) { 
      UIApplication.shared.open(url!, options: [:], completionHandler: nil) 
     } else { 
      UIApplication.shared.openURL(url!) 
     } 
    } 

    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) { 
     if searchText.isEmpty { 
      filteredData = data 
      Here is where I am getting "Cannot Assign Value Type"^^^ 
      On the filteredData = Data 
     } else { 
      filteredData = data.filter { $0.name.range(of: searchText, options: .caseInsensitive) != nil } 
      Then right here I am getting "Cannot invoke 'filter' with an argument list of type."^^^ 
     } 
     tableview.reloadData() 
    } 

    func searchBarTextDidEndEditing(_ searchBar: UISearchBar) { 
     searchBar.showsCancelButton = true 

    } 

    func searchBarCancelButtonClicked(_ searchBar: UISearchBar) { 
     searchBar.showsCancelButton = false 
     searchBar.text = "" 
     searchBar.resignFirstResponder() 
    } 
}

필터링 된 데이터 형식은 데이터와 동일해야하며 [TableItem]이어야합니다.
