Could not find or use auto-linked library '..." after installing react-native-fbsdk

Question

I am trying to install react-native-fbsdk via npm, and whereas my build worked perfectly before, once I install the library and install pods, I get the following error:

... etc

I've searched everywhere for a solution to this problem and I am not seeing how to solve this library issue.

I am on React Native .60.5 - is there any solution for this problem?

Which React-Native version does the FBSDK version you installed support? You may need to either downgrade FBSDK or upgrade RN. — V. Dimitrov, May 25 '20 at 00:24
It have same problem on [github](https://github.com/facebook/react-native-fbsdk/issues/755), but there are no answer now. — 高鵬翔, May 25 '20 at 01:01
Temporarily downgrading to v1.1.2 of react-native-fbsdk and 5.8.0 of fbsdk has solved the issue — Steven Matthews, May 25 '20 at 02:24

To resolve this problem you just need to add swift file and ** "Create Bridging Header"** in your Xcode project.

open Xcode and under you project select New file and select swift file
now clean your build and make new build.

Or you can see bellow link to understand this so well

I fixed this by adding a .swift file via xcode

open XCode project
create new file, select swift file
confirm "Create Bridging Header"
clean
build

I tried a few combinations of these steps but found I needed all of them (ie. it must be done via xcode, you do need the bridging header, and you do need to clean the build folder).
