编译构建失败时出现xcode错误

Question

I'm doing an app using firebase, I've already done the set up with pod and today when I re-opened the project after a bit of time I have this problem in the picture, any help on how to fix it?

I've already tried to clean and deleting pod files and re-executing a "pod install" but it seems he can no longer see my "import Firebase"

Unfortunately there could be a number of reasons for your error. Here are a couple easily overlooked steps when installing Firebase with cocoapods:

1. The top of your pod file likely looks similar to the snippet below. It appears you're using swift so make sure you uncomment the "use_frameworks!" line as I've done here :

    # Uncomment this line to define a global platform for your project # platform :ios, '10.0' # Uncomment this line if you're using Swift use_frameworks! 

2. Make sure from now on you open your project from the terminal:

    $ open your-project.xcworkspace 

3. If you still don't have any luck it may be worth carefully reviewing the getting started guide for Firebase: Add Firebase to your iOS Project
