Google cloud firestore 将数据从SwiftUI更新到Firestore数据库

我正在开发一个swiftui应用程序，它可以流式播放电影，并链接到Firebase。目前，我正在尝试获取视频暂停的时间（通过AVPlayer），并将其更新到我的数据库时间字段，以便用户可以从停止的地方开始。我正在尝试使用可编码格式更新数据，并已导入FirebaseFirestoreSwift。但是，代码没有对数据库进行任何更改，因此我想知道是否可以获得帮助。从数据库查询数据的工作非常完美，我只需要关于如何从SwiftUI更新电影集合的不同字段的指导。非常感谢

import FirebaseFirestoreSwift

...

@State var SectionX: movies

....

//when video is ended record time and update value to firestore time field

.onDisappear {
          avPlayer.pause()
                                    
          let db = Firestore.firestore()
          let currentTime = Float(avPlayer.currentTime().seconds)
                                   
          print(currentTime)

          db.collection("movies").document(SectionX.id)
          SectionX.time = String(currentTime)

          func updateTime(_ mov: movies) {
              do {
                   let _ = try db.collection("movies").document(SectionX.time).setData(from: currentTime)
                 }
              catch {
                       print(error)
                 }
          }
}

            }

开始工作了！只需要使用updateData方法

let x = db.collection("movies").document(SectionX.id).documentID                                  
db.collection("movies").document(x).updateData(["time":currentTime])
