How to store custom object in Firebase with Swift?

问题

I'm porting an android app and using firebase in android it is possible to save a format in this way. How can i do this on Swift? I read that i can store only this kind of data

• NSString
• NSNumber
• NSDictionary
• NSArray

How can I store the obj in atomic operation? It's correct to store every field of the user object in separate action?

Firebase on Android

mDatabaseReferences.child("users").child(user.getUuid()).setValue(user)

I generally store objects as dictionaries on firebase. If, within my application, I have a User object, and it has properties as such:

class User {
var username = ""
var email = ""
var userID = ""
var consecutiveDaysLoggedOn = Int()
}



let newUser = User()
   newUser.username = "LeviYoder"
   newUser.email = "LeviYoder@LeviYoder.com"
   newUser.userID = "L735F802847A-"
   newUser.consecutiveDaysLoggedOn = 1

I would just store those properties as a dictionary, and write that dictionary to my firebase database:

let userInfoDictionary = ["username" : newUser.username
                           "email" : newUser.email
                           "userID" : newUser.userID
              "consecutiveDaysLoggedOn" : newUser.consecutiveDaysLoggedOn]

let ref = Database.database().reference.child("UserInfo").child("SpecificUserFolder")
//      ref.setValue(userInfoDictionary) { (error:Error?, ref:DatabaseReference) in

ref.setValue(userInfoDictionary, withCompletionBlock: { err, ref in
    if let error = err {
        print("userInfoDictionary was not saved: \(error.localizedDescription)")
    } else {
        print("userInfoDictionary saved successfully!")
    }
}

Does that address your question?

Use

self.ref.child("users").child(user.uid).setValue(["username": username])
