Добавить searchBar как subview navigationBar

.
    navigationController?.navigationBar.isTranslucent = false
    navigationController?.navigationBar.setBackgroundImage(UIImage(), for: .default)
    navigationController?.navigationBar.barStyle = .black
    navigationController?.navigationBar.barTintColor = UIColor.red
    navigationController?.navigationBar.shadowImage = UIImage()
    title = "User profile";

    let searchBar = UISearchBar()
    searchBar.placeholder = "Search"
    searchBar.frame = CGRect(x: 0, y: 0, width: (navigationController?.view.bounds.size.width)!, height: 64)
    searchBar.barStyle = .default
    searchBar.isTranslucent = false
    searchBar.barTintColor = UIColor.red
    searchBar.backgroundImage = UIImage()
    view.addSubview(searchBar)

Конечно Swift, все остальное разве что только для простеньких приложений

На серваке

var app = require('express')()
var server = require('http').Server(app)
var io = require('socket.io')(server)

server.listen(3000)

io.on('connection', function(socket) {
  socket.on('comment', function(data) {
    io.emit('comment', data)
  })
}

На клиенте

socket.on("comment") {[weak self] data ,ack in
// получаешь комменты
}

Почему просто не сохранять видео в Document Directory и потом просто не передать путь в AVPlayer?

var inputScoreArr: [String] = []
        
        func finish() {
            for row in 0...usersIn.count {
                let indexPath = IndexPath(row: row, section: 0)
                let cell = tableView.cellForRow(at: indexPath) as! InputScoreTableViewCell
                inputScoreArr.append(cell.inputScore.text)
            }
        }
