firebase uid总是返回零

Question

她是我的数据库/规则：

{
  "rules": {
    ".read": true,
    ".write": true
  }
}

我正在尝试两种方式它给我nil

 FIRAuth.auth()?.createUser(withEmail: email, password: pass, completion: { (firuser, error) in

     if error != nil {
    print("error goes when try to user authenticated :) \(error)")
  }

  print("firuser : \(firuser)")

  print("FIRAuth.auth()?.currentUser?.uid : \(FIRAuth.auth()?.currentUser?.uid)")

  print("firuser?.uid : \(firuser?.uid)")

  guard let userUID = firuser?.uid  else{
     print("user UID  not found. should go stackoverflow ")
  return
  }

      guard let userUID = firuser?.uid  else{
         print("user UID  not found. should go stackoverflow ")
      return
      }
})

控制台日志：
