After upgrading to Xcode 12.4, I can no longer seem to embed and code sign a third party static library. This wasn't a problem before, so I think something has changed and I can't work out how to build the app with the library present. Under Signing & Capabilities, and Hardened Runtime, I can get the app to build and run by checking the box for Disable Library Validation. But that doesn't seem to work if I send my app out to others who don't have the static library already installed.
