using an xcframework supplied by 3rd party.
I can build/run/install the app and use the framework without issue when running/installing from Xcode. However if I create an archive and then attempt to upload it to TestFlight I get two errors, the first is:
CFBundelIdentifer Collision. There is more than one bundle with the CFBundelIdentifer value bundleidofframework under the application
And the second is
Invalid Bundle. The bundle at ...myextension.appex contains disallowed file Frameworks.
(I'm using the framework within both the app and an extension)
Within the embed frameworks section of Xcode, the tickbox code sign on copy is ticked (that's the default value and if its unticked then the app doesn't run when installed directly via Xcode).
