UISearchBar: passing data between ViewControllers; Title that is clicked on does not correspond with data that is shown in ListViewController (Swift)

• paste with Paste and Match Style

• use the code formatter tool (<>)

• remove unnecessary empty lines

Code Block 
struct Category {
     let title: String
     let items: [String]
}
//Data (Array: derived from Struct) Code:
let data: [Category] = [
     
     Category(title: "Ann Arbor", items: ["Ann Arbor is a city located in Michigan.", "Population: 119,000", "University: University of Michigan is located in Ann Arbor.",]),
     
     Category(title: "Los Angeles", items: ["Los Angeles is a city located in California.", "Population: 3,900,000,", "University: University of California of Los Angeles",]),
     
     Category(title: "New Haven", items: ["New Haven is a city located in Connecticut.", "Population: 130,000 ","University: Yale University",]),
     
     Category(title: "New York City", items: ["New York City is located in New York.", "Population: 8,300,000","University: Columbia University",]),
     
     Category(title: "San Fransisco", items: ["Ann Arbor is a city located in Michigan.", "Population: 881,000","University: University of San Francisco",]),
]
/ /titledata (Array) Code:
let titledata = ["Ann Arbor", "Los Angeles","New Haven", "New York City", "San Fransisco"]
//filteredData var:
var filteredData: [String]!
// in viewDidLoad func:
filteredData = titledata
// Note: SearchBar Delegate linked in Storyboard.
// UISearchBar Code:
func searchBar( searchBar: UISearchBar, textDidChange searchText: String) {
     
     filteredData = []
     if searchText == "" {
          filteredData = titledata
     } else {
          for info in titledata {
               if info.lowercased().contains(searchText.lowercased()) {
                    self.tableView.reloadData()
                    
                    filteredData.append(info)
                    self.tableView.reloadData()
               }
          }
          
     }
     
     self.tableView.reloadData()
     
}
// didSelectRowAt Func:
func tableView( tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
     
     let category = data[indexPath.row]
     let vc = ListViewController(items: category.items)
     
     vc.title = category.title
     self.navigationController?.pushViewController(vc, animated: true)
}
//numberOfRowsInSection func:
func tableView( tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
     
     return filteredData.count
}
//cellForRowAt func:
func tableView( tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
     
     let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! MyTableViewCell
     cell.myLabel.text = filteredData[indexPath.row]
     cell.myImg.image = UIImage(named: filteredData[indexPath.row] + ".png")
     
     return cell
}

• indexPath.row is 0 (you click on the first displayed row)

• you use data and not filtered Data, hence you get Ann Arbor.

Code Block 
     let category = filteredData[indexPath.row]

Code Block Swift
let category = data[indexPath.row]

Code Block Swift
let category = filteredData[indexPath.row]

Code Block 
func tableView( tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
     
	 let title = filteredData[indexPath.row]		// with row == 0, that should be New Haven (index 0 and not 1) 
	// Find which data it is
	let index = data.firstIndex{$0.title == title} ?? 0
     let category = data[index]
     let vc = ListViewController(items: category.items)
     
     vc.title = category.title
     self.navigationController?.pushViewController(vc, animated: true)
}
