swift firebase query returns null with currentUser?.uid

let userID  = Auth.auth().currentUser?.uid
ref.child("players").child(userID!).observeSingleEvent(of: .value, with: { (snapshot) in

    let value = snapshot.value as! NSDictionary
    print("DICT VALUE",value)
})

I'm trying to get the profile of my signed in user. My issue is that if is use the variable userID let userID = Auth.auth().currentUser?.uid the snapshot is null. Returns this Snap (feoMdSquBSMHFXcPhZKbpsIGlKe2) <null> if I use the literal string let userID = "feomdsqubsmhfxcphzkbpsiglke2"for the userID child I get the expected return 

Snap (feomdsqubsmhfxcphzkbpsiglke2) {
    currentSelected = 0;
    email = "[email protected]";
    uid = feoMdSquBSMHFXcPhZKbpsIGlKe2;
    username = "player 2";
}

I can confirm the userID is valid

let userID  = Auth.auth().currentUser?.uid
print(userID!)

returns feoMdSquBSMHFXcPhZKbpsIGlKe2

here is the data that is stored

{
  "players" : {
    "feomdsqubsmhfxcphzkbpsiglke2" : {
      "currentSelected" : false,
      "email" : "[email protected]",
      "uid" : "feoMdSquBSMHFXcPhZKbpsIGlKe2",
      "username" : "player 2"
    },
    "o4azcazrxjqc3toybykk0ghbd9o2" : {
      "currentSelected" : false,
      "email" : "[email protected]",
      "uid" : "O4aZCAZrXJQc3TOYbykK0ghbD9O2",
      "username" : "player 1"
    }
  }
}

If I remember correctly, Firebase Database keys are case sensitive. In your database, your userID is:

feomdsqubsmhfxcphzkbpsiglke2

However, the actual userID of whatever user you are signed in as is:

feoMdSquBSMHFXcPhZKbpsIGlKe2

Try this:

let userID = feoMdSquBSMHFXcPhZKbpsIGlKe2
ref.child("players").child(userID!).observeSingleEvent(of: .value, with: { (snapshot) in
    let value = snapshot.value as! NSDictionary
    print("DICT VALUE",value)
})

and see what it gives you. If it doesn't work, you know that you have to watch the case of all your characters.
