问题
I am trying to manually import and use the Firebase framework in my iOS application. I am starting off with the basic bare minimum Analytics framework (then I'll add the rest of the frameworks).
I followed this tutorial in order to manually import the Google Firebase framework into my Xcode project. The problem is that I am still getting the following error:
'FirebaseCore/FirebaseCore.h' file not found
I have imported the frameworks, imported the overall header file and have made sure that the files where actually copied to the project directory folder.
I have set the -ObjC linker flag too.
Has anyone else managed to manually import the Google Firebase framework into their Xcode project? What am I missing?
Note: I am not interested in using CocoaPods at all, I just want the simple old fashioned approach.
回答1:
Please check on edit scheme -> build -> check if Find implicit Dependencies is enable. if no, enable it and rebuild.

Faced the same problem you can use the below steps which worked for me.
Step 1: Quit Xcode Delete ~/Library/Developer/Xcode/DerivedData and delete the derived data. Then run.
Step 2: If you're getting this error trying to import a dynamic framework, make sure the framework is included in the target's Target Dependencies.
Project > "Target" > Build Phases > Target Dependencies

There were two problems:
1) The instructions stated on the Google Developer website for importing the frameworks manually, are somewhat lacklustre. So I followed the following tutorial to import the frameworks and setup my developer account: http://www.mokacoding.com/blog/setting-up-firebase-without-cocoapods/
2) After you have imported all the frameworks/resources/plist files/etc... you will still get the following build error:
'FirebaseCore/FirebaseCore.h' file not found
In order to get around this issue, clean your Xcode project and then close the project. Then reopen the project and rebuild it. It will now work - perhaps the Xcode project can now see the framework files or something... not really sure, but it's the only solution that has repeatedly worked for me.
Update
I think this was just a bug with Xcode 9.x, ever since I upgraded to Xcode 10, I haven't had this issue at all. Just import all the frameworks as usual and build and run the project.

Try remove the Podfile.lock file and Pods folder.
Run pod install.
This worked for me.
回答5:
I had the same issue.
It worked for me when I changed
#import <FirebaseAuthInterop/FIRAuthInterop.h>
to
#import "FIRAuthInterop.h"

Make sure you are opening the .xcworkspace file instead of the .xcodeproj file.
I was troubleshooting for at least an hour before I determined this was my mistake, so hopefully this answer will save you some time!
