Problem:

You use the event type .childAdded for observing

case childAdded is fired when a new child node is added to a location

Solution:

You should change the event type from .childAdded to .value like this:

FIRDatabase.database().reference().child("users").child("g373gSvDcFhXNAGh5V6vg7sU5C02").observe(.value, with: { (snapshot) in

  // other code

})
