将Swift中的日期和小时保存到Firestore文档

import Firebase
import FirebaseFirestore

let db = Firestore.firestore()

let currentDate = Date()

let formatter = DateFormatter()
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"

let dateString = formatter.string(from: currentDate)

let data = [
    "date": dateString
    "hour": Calendar.current.component(.hour, from: currentDate)
]

let collectionRef = db.collection("your_collection_name")
let documentRef = collectionRef.document("your_document_name")

documentRef.setData(data) { (error) in
    if let error = error {
        print("Error writing document: \(error)")
    } else {
        print("Document successfully written!")
    }
}
