赞赏这是一个较老的问题，但是从评论中可以看出，一样。只要您使用Google和Firebase pod的最新版本，就应该能够一起使用这两者。

如果你引用了一些不存在的东西，可能会造成困难的事情之一。例如，如果您包含 pod'Google \ AppInvite'，那么CocoaPods将使用旧版本的Google pod，如 AppInvite subspec no更长的时间在这种情况下，您需要更新到 pod'Firebase \Invites'。

您可以在 iOS迁移指南。

最后，记得运行 pod update ，以确保你拉下依赖的最新版本，而不是只是 pod install 。

您仍然遇到问题，请发布您的Podfile，并检查您的Podfile.lock，以查看Google和Firebase Pod的版本号。

解决方案

Appreciate this is an older question, but judging from the comment other people have hit the same thing. You should be able to use the two together, as long as you're using the most recent versions of both the Google and Firebase pods.

One of the things that might make that difficult is if you're referencing something that doesn't exist any more. For example, if you include pod 'Google\AppInvite' then CocoaPods will use an older version of the Google pod, as the AppInvite subspec no longer exists. In that case you need to update to pod 'Firebase\Invites'.

You can see a full list of what the updated dependencies should be in the iOS migration guide.

Finally, remember to run pod update to ensure you pull down the latest versions of the depedencies rather than just pod install.

If you're still having trouble, please post your Podfile, and check your Podfile.lock to see what version numbers of the Google and Firebase pods you have.
