Xcode 12.3 Mac Catalyst code signing fails (code object is not signed at all)

Question

When I try to submit my app to AppStore for Mac Catalyst I get code signing error below. I have no idea how to solve the problem, I have googled everything I found and couldn't find a solution.

Submitting iOS version works without any problems.

(Xcode 12.3 & Big Sur 11.1.)

Any ideas?

In your target’s Frameworks and Libraries settings, what do you have selected for BBMetalImage’s Embed option? Unless you’re not including BBMetalImage that way. — Adam
All third-party libraries I have installed via CocoaPods. What/where could I check what you are asking? — sabiland
Sorry, I don’t use CocoaPods so I don’t know how you check their configuration. But those errors look like the framework is being embedded and/or signed when it shouldn’t be, or isn’t being signed correctly. But like I said, I don’t know how CocoaPods handles that. — Adam
Creating new provisional profile in developer account and install in your keychain. That worked for me. — Manish

Stripping the bitcode from the catalyst slices of the framework fixed the error.

So in this case:

xcrun bitcode_strip -r BBMetalImage -o BBMetalImage

inside the ios-arm64_x86_64-maccatalyst directory of the .xcframework that the project includes.
