Dynamic framework with static framework dependency results in duplicate classes

What did you do?

Created a dynamic framework that includes a static framework in its Linked Frameworks and Libraries section. The static framework dependency is provided by a 3rd party and is closed source. Run pod install on my podspec that lists the static framework dependency as a vendored_framework.

What did you expect to happen?

Vendored frameworks installed without duplicate classes warning.

What happened instead?

When running the application in Xcode after doing the pod install, I get the following runtime warnings:

This comment from a previous issue says that using inherit! :search_paths should prevent the static framework from being linked to the app target, but that doesn't seem to be working for me.

The linker does not support dynamic library dependencies on static libraries. With CocoaPods 1.4.0, you can use the static_framework podspec attribute to build a pod itself as static and have static library framework dependencies.

@dnkoutso any suggestions? I linked to one of your comments that I thought indicated a fix for my issue.
