Value of type 'User' has no subscripts

问题

I am trying to create a UITableView on my IOS app that displays a list of all the app's registered users from Firebase and includes a UISearchBar to search through them. I am very new to this and unfortunately this code is giving me the following error: "Value of type 'User' has no subscripts" on the line of code "let user = users[indexPath.row]"

There is an NSObject User class in another file that defines name and email as String?

These are the variables:

var searchActive : Bool!
var userList = [User]()
var filterUsers = [User]()
private var users = User()
private var hasFetched = false

Here is the search bar function I was using that is giving me the error:

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

    filterUsers = userList.filter({ (text) -> Bool in

        let temp: NSString = text.name! as NSString
        let range = temp.range(of: searchText, options: NSString.CompareOptions.caseInsensitive)
        return range.location != NSNotFound

    })

    if(filterUsers.count == 0){
        searchActive = false;
    } else {
        searchActive = true;
    }
   //refreshTable()
    
    func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1
    }

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        if(searchActive) {
            return filterUsers.count
        }
        return userList.count;
    }

   func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        
        if let user = userList[indexPath.row] as? [String : AnyObject] {
        }
    
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell")! as UITableViewCell;
        let user = users[indexPath.row]
        cell.textLabel?.text = user.name
        cell.textLabel?.text = user.name
        

        return cell;
    }

} }

回答1:

Modify this:

let user = users[indexPath.row]

To this:

let user = searchActive ? filterUsers[indexPath.row] : userList[indexPath.row]
