ios - Removing All Items Under A Node Firebase -

-

i trying remove children under node. there way delete items under node? structure like:

lastmessages   - mainid     - timestampedid       - keys:values

what want is, using mainid, delete items under it. there's 1 timestampedid @ time lastmessages. that's why thought should delete items under mainid before writing new value. there way achieve that; or there better ways thought?

let ref = firebase(url: path) let myref = ref.childbyappendingpath(mainid)     // how delete items under myref?

simply call myref.removevalue()

explained in docs

the simplest way delete data call removevalue on reference location of data.
