未声明Firebase参考 [英] Firebase References undeclared

问题描述

我创建了一个新的Xcode项目，将"Firebase" pod添加到我的pod文件中并安装了它，并根据Firebase文档添加了Google-services.plist文件和其余的文件.

I created a new Xcode project, added the 'Firebase' pod to my pod file and installed it, and added the Google-services.plist file and the rest according to the Firebase documentation.

导入Firebase 工作正常，但如果我尝试

import Firebase works fine, but if I try

var ref:FIRDatabaseReference!

在同一个ViewController中，则会引发错误:

in the same ViewController, then it throws an error:

使用未声明的类型'FIRDatabaseReference'

Use of undeclared type 'FIRDatabaseReference'

对于任何Firebase参考，都会发生这种情况.有什么想法吗?我是Swift和xCode IDE的新手.

And this happens for any Firebase References. Any ideas on this? I am very new to Swift and the xCode IDE.

推荐答案

遇到了同样的问题，但是过了一会儿，我意识到我在Pod文件中缺少一个条目，您的Pod文件应该包含:

Just had the same problem, but after a while I realized that I was missing an entry in the pod-file, your pod-file should contain:

pod 'Firebase/Database'

希望它现在可以工作:)

Hope it works now :)
