You checked if the user email was verified even before signing them in.

This is what worked for me.

    FIRAuth.auth()?.signInWithEmail(txtUsername.text!, password: txtPassword.text!) {
        (user, error) in
        if let user = FIRAuth.auth()?.currentUser {
            if !user.emailVerified{
                let alertVC = UIAlertController(title: "Error", message: "Sorry. Your email address has not yet been verified. Do you want us to send another verification email to \(self.txtUsername.text).", preferredStyle: .Alert)
                let alertActionOkay = UIAlertAction(title: "Okay", style: .Default) {
                    (_) in
                        user.sendEmailVerificationWithCompletion(nil)
                }
                let alertActionCancel = UIAlertAction(title: "Cancel", style: .Default, handler: nil)

                alertVC.addAction(alertActionOkay)
                alertVC.addAction(alertActionCancel)
                self.presentViewController(alertVC, animated: true, completion: nil)
            } else {
                print ("Email verified. Signing in...")
            }
        }
    }
