Found an unexpected Mach-O header code: 0x72613c21 in Xcode10 with FBSDKCoreKit.framework

Question

I have a project using the latest version of the FacebookSDK and Xcode 10, the project runs OK in devices, but when submitting to the App Store, during during validation the following error occurs:

Found an unexpected Mach-O header code: 0x72613c21.

The log shows:

I have tried deleting frameworks from Embed Frameworks and adding in Link Binary With Libraries, and changing the Mach-O type of the framework. But the error isn't gone

I came across this issue today while adding the FacebookSDK to an iOS project manually, without using CocoaPods.

I am assuming you have downloaded the SDK directly from Facebook.

The Facebook frameworks are static frameworks (not dynamic) so the correct way to integrate them is to include each framework in the "Link Binaries With Libraries" build Build Phase for your target, but nowhere else. Do not add them to the Embed Frameworks step.
