Firebase : Retrieve childByAutoID from Realtime Database

I'm currently learning the ropes of Firebase and iOS so please bear with me. I'm currently posting to my table called

as shown here:

let postInfo = ["Description": txtPostDescription.text!, "ImageUrl": imgUrl, "Likes": 0]

var t = FIRDatabase.database().reference().child("Posts").childByAutoId().setValue(postInfo)


I'm trying to retrieve the
primary key
that gets created when I insert the new record, however I'm unable to retrieve it. I've tried
(but that was a random guess due to browsing the web and not being able to find a solid solution). Any ideas?

let postInfo = ["Description": txtPostDescription.text!, "ImageUrl": imgUrl, "Likes": 0]

var reference  = FIRDatabase.database().reference().child("Posts").childByAutoId()

let childautoID = reference.key 

Note :- Althogh childByAutoId() is a great functionality from Firebase.But prefer timestamps to store the data into when you want to create a node with a unique key.The reason why i prefer timestamps is because they can also be helpful in sorting of data...But thats just me..

Alternative :-

let timeStamp = Int(NSDate.timeIntervalSinceReferenceDate()*1000) //Will give you a unique id every second or even millisecond if you want..
