我将旧应用程序更新为swift 3并且我有一些迁移错误.在这部分代码上:

func done(_ request: URLRequest?, response: HTTPURLResponse?) {
    let visibleCells = tableView.visibleCells as! [NewsStoryCell]
    let cells = visibleCells.filter({ $0.news.thumbUrl == request?.URLString })

    if let cell = cells.first {
        cell.reloadThumbImage()
    }
}

我有错误:

"URLRequest"类型的值没有成员"URLString"

上:

$0.news.thumbUrl == request?.URLString
