iOS Firebase : Add data to firebase node of array type

Question

I got node in the firebase named "XXXXX". I want to add tokenids to this node.

But in iOS I am having problem updating tokensids.

Do we got functions in iOS for appending data to iOS Firebase?

or we have to first get the token from firebase , append our token and save the token array back to node ?

Any suggestion guys ?

No, you cannot append data to an array in Firebase using any Firebase query.

But, there is a way by using dictionary as arrayObjectToAdd: true,

self.ref.child("ArrayMainNode").setValue(["arrayObjectToAdd": "true"])

To remove an array object, you can directly use

self.ref.child("ArrayMainNode").child("arrayObjectToAdd").removeValue()

"No, you cannot append data to an array in Firebase using any Firebase query." are you sure in it?

you can store an array , replace an entire array but not append an object to array in Firebase. I have tried and this is the best solution, one which even Firebase supports.

github.com/Pulichev/RideWorldIOs/blob/VladPulichev/RideWorld/… - 57 line. Function. Working. "/posts/" is array. I'm not trying to be rude btw:)

But we both are saying the same thing. We need to add the object to the array as { object : true }. There isn't any Firebase method to append object to Array.

You can do it this way:

let ref = FIRDatabase.database().reference(withPath: "somePath/array").child(newArrayObjectKey)
ref.setValue("true") // or whatever

Hope it helps

You can do it by this way:

let refInsert = Database.database().reference()

self.refInsert.updateChildValues(["Your node": "\(new token)"])
