Bypass unique auto ID created by Firebase. Swift 3.0

Question

When I upload an Image, it is automatically update to database child(user.uid).child(newImage).childAutoID.setValue() This is my json node

Users
  WOhpPzlHCzYximWyBXas3Prg2rL2
     NewImage
       -KSE4ZcvqhFeWmuRQjjI
       -KSEGLazKbfPePkCBFbe
       -KSEGNVimH7GACRyXbo4
       -KSEGO4gfLGOv0erTXA5
       -KSENPeq7Oa5cru7gKum

Inside one autoID, This is the Json tree

-KSE4ZcvqhFeWmuRQjjI
    DownloadUrl:  "abcd.com"
    timestamp:    21-09-2016

When I try to get value from DownloadUrl, I use child("Users") but can't child through user uid, anyways I can't child through autoUID which is created by Firebase. Does anyone have any experience. Thank you

Instead of describing your code, edit your question to include the minimum, complete code that is needed to reproduce the problem. — Frank van Puffelen, Sep 22 '16 at 04:22

Swift 2:

FIRDatabase.database().reference().child("Users/\(FIRAuth.auth()!.currentUser!.uid)/NewImage").observeSingleEventOfType(.Value , withBlock : {(imagesSnap) in 

    if let imagesDict = imagesSnap.value as? [String:AnyObject] {
       for each in imagesDict{
           print(each.0) // your autoId
           print(each.1) // your imageDetails for that autoId  
           }
    }
})

Swift 3:

FIRDatabase.database().reference().child("Users/\(FIRAuth.auth()!.currentUser!.uid)/NewImage").observeSingleEvent(of: .value, with : {(imagesSnap) in

        if let imagesDict = imagesSnap.value as? [String:AnyObject] {
        for each in imagesDict{
        print(each.0) // your autoId
        print(each.1) // your imageDetails for that autoId
        }
       }
     })

But if you are looking for the autoID that contains a specific key value pair Read last part of this answer
