Firebase Retrieving Data in Swift

Question

I\'m trying to retrieve specific data from just the currently logged in user. My data in my database looks like this:

Answer 1

{
    "rules": {
         "tbl_name": {
            ".indexOn": ["field_name1", "field_name2"]
         },
    ".read": true,
    ".write": true
    }
}

You can apply indexOn on any field. Add this json in rules security and rules tab. Hope this works for you. :)
