Firebase issuing out 2 different uid's -Swift iOS

Question

I have all my pods correctly installed. My app launches and then when I get to scenes that have to access Firebase I've noticed there's a crash. The reason seems to be that Firebase is issuing me 2 different uid's and the one in Auth doesn't match the one in the Database.

When my app launches in AppDelegate I have code to get the current uid.

//This is in App Delegate
let myUserID = FIRAuth.auth()?.currentUser?.uid

print("App Delegate: UID is (myUserID!)")
//An example print is 'App Delegate: UID is Abcdefg12345'

Next a SignUp scene is presented and in that view controller I have

FIRAuth.auth()?.createUserWithEmail(self.emailTextField.text!, password: self.passwordTextField.text!, completion: {

            //You can access the newly issued uid from user via user!uid
            (user, err) in

print("SignUp: UID is (user!uid)
")
//An example print is 'SignUp: UID is Vwxyz67890'

When I access user!uid (from user) I get a totally different uid from what is originally in the AppDelegate.

However the uid that I get from user in FIRAuth.auth()?.createUserWithEmail is what's current in Auth but is not recognized in FirebaseDatabase.

The odd thing is the uid that is printed in AppDelegate is what's current in the FirebaseDatabase but is not recognized in Auth. If this uid is changed upon signing up then it should not be available in the Database

I also have a logout scene and when I press the logout button I get the logout uid as the same one created in FIRAuth.auth()?.createUserWithEmail

Any ideas why I have 2 different uid's? This seems to be my crash issues.

print("Now Look at the UID printed from the above property myUserID: (self.myUserID)")

if err != nil{
        print((error?.localizedDescription)

       }

let usersRef = self.dbRef.child("users")

let email = self.self.emailTextField.text!
let dict = [String:AnyObject]()
dict.updateValue(email, forKey: "emailKey")
dict.updateValue(self.myUserID!, forKey: "userIDKey")
