Header file (FirebaseCore/FirebaseCore.h) not found, despite importing Firebase.framework

Question

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.

Answer 1

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.
