[swift-evolution] [swift-build-dev] [Review] SE-0149 Package Manager Support for Top of Tree development

[Boris Buegling]

Hi Derrick,

I think you meant to send this as a reply to SE-0149 Package Manager Support for branches, correct?

I’m not quite sure about the use case for your described behaviour, can you elaborate a bit more why you would want to override a dependency of A from the manifest of P? 

If the goal is a temporary override, the proposal already allows that by utilising `pin --branch`.

Cheers,
Boris
