swift - Firebase Firestore 时间戳至今问题

Question

将我的代码升级到 Swift 5 后，Firestore 将 NSDate 返回为 FIRTimestamp。当我尝试将其作为 Date 接收时，它会抛出错误:

Could not cast value of type 'FIRTimestamp' (0x107aab8c0) to 'NSNumber' (0x10b8fbe00).

如何解决这个问题？

Answer 1

以下代码用于从 Firestore 获取时间戳值并将其转换为 NSDate

let timestamp: Timestamp = (filteredtotalArray[indexPath.row] as AnyObject).value(forKey: "requestedDate")! as! Timestamp
let RequestedDate = timestamp.dateValue()
