I'm making an app with a login page, which I want it to retrieve a username of a user from a set of user data in realtime firebase, but when I run the code and sign in as an account it displays
Snap (n9fd2UynzZT6rLXRs4puqYahWUk2) < null > Func Code:
func checkIfUserSignedIn(){
				if Auth.auth().currentUser?.uid == nil{
						logout()
				}else{
						let uid = Auth.auth().currentUser?.uid
						Database.database().reference().child("users").child(uid!).observeSingleEvent(of: .value, with: { (snapshot) in
								
						print(snapshot)
										
						}, withCancel: nil)
						
				}
		}
JSON
{
	"Test" : {
			
		"users" : {
			"guest" : {
				"email" : "guest@test.com",
				"name" : "guest",
				"uid" : "n9fd2UynzZT6rLXRs4puqYahWUk2"
			},
			
			"guest2" : {
				"email" : "guest2@test.com",
				"name" : "guest2",
				"uid" : "r5WS623Cg7UL0UPSoq0S61sJj8Z2"
			}
		}
	}
Selecting any option will automatically load the page
