Basically I am checking if some data exist in the firebase database or not using Database.database().reference().child(“users”).hasChild(“somename”)
if it has that some name then i want to write to three different node on firebase i.e at sender node at receiver node and at one more node
i am doing this by calling

 Database.database().reference().child(“send).childbyautoid.servalue(somename: somevalue)
 Database.database().reference().child(“receiver”).child(“receiverid”).childbyautoid.setvalue(somename: somevalue)
 database.database.reference().child(“all”).childbyautoid.setvalue(somename: somevalue)

problem is i am doing it just before closing the view controller
so either i should wait for all of the fire to execute or controller dismisses only after calling one fire
is this a bad design what should i do to close the controller immediately and also get the data at three places on firebase

You can perform multiple writes in one go by using a multi-location update. In your code that would look something like this:

let rootRef = Database.database().reference()
let pushId = rootRef.childByAutoId().key
let updatedUserData = [
 "send/(pushId)/someName": someValue, 
 "receiver/(pushId)/someName": someValue,
 "receiver/(all)/someName": someValue
]
// Do a deep-path update
rootRef.updateChildValues(updatedUserData, withCompletionBlock: (error, ref) -> Void in
 if (error) 
 print("Error updating data: (error.description)")
 
)

The completion handler is then also the place where you'd put code that needs to run when the write is done.
