2019.3 - validation on upload to store gives "UnityFramework.framework contains disallowed file"

App runs on phone normally.
When trying to validate the app before uploading it to the store, this comes out:

Invalid Bundle. The bundle at 'my.app/Frameworks/UnityFramework.framework' contains disallowed file 'Frameworks'

Unity 2019.3 Xcode 10.2

Help?
