[OSX] Umbrella header for module 'FBLPromises' does not include header '/Headers/PromisesObjC-umbrella.h'

Hi, I'm sorry to cross post this with stackoverflow, but there was no tag related to google-promises.

I'm working on a framework that uses promises internally, and I'd like the framework to work cross platform for iOS, macos and tvOS.

When building my framework for distribution with cocoapods, the lint check is failing specifically for macos, but not the other platforms.

I've described the error in this ticket: https://stackoverflow.com/questions/58171317/umbrella-header-for-module-fblpromises-does-not-include-header-headers-promi

If I can get some help, i'd very much appreciate it.
