如何使用swift以swift字典格式创建类型为storage reference的字段.我不断收到错误消息，说是FIRStorageReference.预先感谢您的帮助. 这是下面的代码，photoRef是存储引用:

How do you create a field of type storage reference in the swift dictionary format using swift. I keep on getting an error saying that FIRStorageReference. Thank you in advance for your help. This is the code below, photoRef is a storage reference:

let newFirePhotoRef = newUserRef.collection("Photos").document()
photoRef = photoRef.child(newFirePhotoRef.documentID)

newFirePhotoRef.setData([
  "Date":Date(),
  "Photo Reference in Storage": photoRef 
])

这是我收到的错误:

由于未捕获的异常'FIRInvalidArgumentException'而终止应用程序，原因:'不支持的类型:FIRStorageReference(在字段Photo Reference in Storage中找到)'

Terminating app due to uncaught exception 'FIRInvalidArgumentException', reason: 'Unsupported type: FIRStorageReference (found in field Photo Reference in Storage)'

推荐答案

let db = Firestore.firestore()
//this is to store reference 
let ref =  db.document("listing/v4/content/\(key)")

let dataToWriteInFireStore :[String:Any] = [
   "_ref": ref,
   "id": 4,
   "timestamp": Int(Date().millisecondsSince1970)
]

db.collection("user_favs/v4/\(FIRUserID)").document("user_fav").setData(dataToWiteInFireStore) {
    err in
    if let err = err {
       print("Error writing document: \(err)")
    } else {
       print("Document successfully written!")
    }

   }
