Firebase:如何获取User.uid? [英] Firebase: How to get User.uid?

问题描述

我正在使用Firebaseauth来管理我的iOS应用程序的用户和数据.用户可以登录，并将他们的userinfo正确存储在数据库中. 但是，当我尝试让用户使用以下字符串在不同的viewController中写入数据库时​​:

I'm using Firebaseauth to manage users and data for my iOS app. The users can log in, and their userinfo is stored correct in the database. But when I try to get the users to write to the database in a different viewController, using this string:

self.ref.child("users").child(user.uid).setValue(["username": username])

抛出的错误是

类型用户没有成员.uid

Type user has no member .uid

我想这很有道理，因为我还没有创建变量.但是我不知道该怎么声明?

That makes sense I guess, since I haven't created the variable. But I can't figure out how to declare it?

推荐答案

这是获取用户uid的方法:

This is how to get users uid:

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