关于 ios：如何在 swift 中使用 FieldValue.serverTimestamp() 将 TimeStamp 分配给 FireStore | 珊瑚贝

let db = Firestore.firestore()
    let settings = db.settings
    settings.areTimestampsInSnapshotsEnabled = true
    db.settings = settings        
    db.collection(THOUGHTS_REF).addDocument(data: [

        CATEGORY : categorySelected,
        NUM_COMMENTS : 0,
        NUM_LIKES : 0,
        THOUGHT_TXT : thoughtTxt.text!,
        TIMESTAMP : FieldValue.serverTimestamp(),
        USERNAME : username

    ]) { (err) in
        if let err = err {
            debugPrint(“Error adding document: \\(err)”)
            return
        }
    }
    self.navigationController?.popViewController(animated: true)
}
