Checklist

• I've updated to the latest released version of the SDK
• I've searched for existing GitHub issues
• I've looked for existing answers on Stack Overflow, the Facebook Developer Community Forum and the Facebook Developers Group
• I've read the Code of Conduct
• This issue is not security related and can safely be disclosed publicly on GitHub

Environment

Describe your dev environment here, giving as many details as possible. If you have them, make sure to include:

• Xcode Version: 11.7 (also tested latest 12.2, same issue)
• Swift Version: 5.2 (also tested latest 5.3.1, same issue)
• Installation Platform & Verison: Swift Package Manager

Goals

The Facebook SDK 6.5.1 works fine in iOS/Catalyst projects as a Swift Package Manager dependency whereas 8.2.0 will compile for iOS but not Catalyst.

Expected Results

To be able to include the Facebook SDK as a Swift Packager Manager dependency in Mac Catalyst apps.

Actual Results

It fails to compile with the error FBSDKCoreKit/FBSDKCoreKit.h file not found in FBSDKCoreKitImport.h

Steps to Reproduce

1. Create a new iOS app with Mac catalyst support (you can use Xcode 11.7 or the latest 12.2, it doesn't matter. Run it on iOS and Mac and it works fine.
2. Add the 8.2.0 Facebook SDK as a Swift Package Manager dependency:
3. When running the iOS target it builds and runs fine but when running the Mac Catalyst target it can't compile the Facebook SDK
4. If you downgrade the dependency to the Facebook SDK 6.5.1 it works on both iOS and Mac Catalyst
