Goals

Integrate facebook SDK into iOS app extension

Expected results

working facebook analytics in iOS app extension

Actual results

I have an iOS keyboard app extension, where I used to initialise facebook SDK for tracking / analytics.
After updating the SDK to the latest version, the app started to crash due to:
'As of v9.0, you must initialize the SDK prior to calling any methods or setting any properties.
After following the latest SDK changes, I was able to fix this issue in the main app by first calling ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions).
However the same can not be done in the app extension due to extensions different lifecycle, in other words in extension you don't have access to UIApplication.
I went through various solutions, but still can't make it work.

Would be great if there was a way to avoid calling ApplicationDelegate method by moving straight to Settings initialisation, which worked for me before the latest SDK changes.
