Is there anything relevant here for Chrome for iOS? I don't think so.

There shouldn't be. This is a Mac bug/feature request, not iOS.

Per kthelgason, the ask in this bug is for the mac_framework_bundle toolchain to output a usable .framework that XCode can directly consume without any further work. Current output is not usable because it does not contain include headers.

[mac triage]

This is probably the support for public_headers that is not implemented for mac_framework_bundle. The iOS version could probably be used as a base.

Removing OS=iOS as iOS is not affected :-)

Please note that https://bugs.chromium.org/p/webrtc/issues/detail?id=6703 has been closed as a duplicate of https://bugs.chromium.org/p/webrtc/issues/detail?id=6706. Also, there are a few other pieces missing from the Mac framework besides Headers directory. I have tried to manually cobble together the necessary parts and can get my application to link but it fails at runtime. Hopefully a properly constructed framework using the proper tools can overcome this issue.

We originally shared ios_framework_bundle and mac_framework_bundle with a shared template, but we split them because there was divergence around fat builds and iOS-specific linking. I'd prefer to not re-merge them.

I don't think it's strictly necessary to add additional support to mac_framework_bundle for this. Can't you accomplish this with just a bundle_data step going into "{{bundle_root_dir}}/Headers/{{source_file_part}}" ?

@rsesek I am not sure if the problem can be fixed by copying the header files. 
Right now I am experiencing signing issues (don't know where these come from) and an error which says "dyld: Library not loaded".

Thanks @polarapp for responding. I think the issue you're looking for is https://bugs.chromium.org/p/webrtc/issues/detail?id=6703#c9 or https://bugs.chromium.org/p/webrtc/issues/detail?id=6706#c7. @rsesek you responded with https://bugs.chromium.org/p/webrtc/issues/detail?id=6706#c9 but I have not been able to figure out what you mean there.

thanks for the clarification rsesek@. It may not be strictly necessary, but is there a good reason not to? Can't the relevant parts of the ios template just be copied over?
I can submit a CL if you're okay with this.

No, I do not want to add more to the base template unless it's actually necessary. Can you copy the headers using just a bundle_data rule?

Sure, that should work also. I will close this issue as wontfix then.
