iOS action extension Cocoapods Podfile FBSDKCoreKit 'sharedApplication' is unavailable - ios

Question

I need the Facebook SDK in both my app and my action extension. I use Cocoapods 1.4.0, Swift 4 and Xcode 9.2. I'm having this error message coming from the FBSDKCoreKit:
'sharedApplication' is unavailable: not available on iOS (App
Extension) - Use view controller based solutions where appropriate
instead.
I've already read a lot of answers, on SOF and Github mainly. I tried a lot of suggestions. But I did not make it work.
My current Podfile:
source 'https://github.com/CocoaPods/Specs.git'
workspace 'MyApp'
use_frameworks!
platform :ios, '10.0'
inhibit_all_warnings!
def my_pods
pod 'FBSDKCoreKit'
pod 'FBSDKLoginKit'
pod 'FBSDKShareKit'
end
target 'MyApp' do
my_pods
end
target 'MyAppExtension' do
my_pods
end
What I tried:
1) set Require Only App-Extension-Safe API to NO (both for my app and the extension).
2) add this to my podfile:
post_install do |installer_representation|
installer_representation.pods_project.targets.each do |target|
if target.name == "Pods-MyAppExtension-FBSDKCoreKit"
target.build_configurations.each do |config|
//I tried both these lines
config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)', 'AF_APP_EXTENSIONS=1']
config.build_settings['APPLICATION_EXTENSION_API_ONLY'] = 'NO'
end
end
end
end

Answer 1

only as documentation if others arrive here:
using SPM and FB SDK 11.0 AND Xcode 12.x it works
using " " AND Xcode 13.beta for iOS13 fails:
'sharedApplication' is unavailable: not available on iOS (App Extension) - Use view controller based solutions where appropriate instead.
PS
it's a shame using objC in 2021... :(
and ridiculous using "SWFT" Package manager containing objC, :(
