Recursive Carthage dependencies

[LinusU]

I'm not 100% if this is within the scope of this project, but currently, when adding Carthage dependencies you also have to manually add any Carthage dependencies that they may in their turn depend on.

E.g. I might have an iOS application that depends on BioPass. I add github "LinusU/BioPass" ~> 1.1.1 to my Cartfile, and - carthage: BioPass to the dependencies in project.yml.

Now, BioPass in turns depends on PromiseKit, and Carthage will correctly pick this up and install both BioPass and PromiseKit. However, trying to run the built app will crash with: Library not loaded: @rpath/PromiseKit.framework/PromiseKit.

The current fix is to add - carthage: PromiseKit to the list in project.yml, and then all is well. However, I think it would be excellent if this could be done automatically, as Carthage does.

I thought XcodeGen shouldn't know about Cartfile.resolved, but it already knows about internal behavior like where carthage frameworks are built (Carthage/Build/$platform) and so on, so I guess this can be within the scope of XcodeGen. 🤔

Thoughts, @yonaskolb ?

[toshi0383]

Oh I realized that it's impossible because we cannot determine which frameworks to go into which target.🙄

[yonaskolb]

Yeah, not sure if we can easily do this

Hello everyone!

Wasn't this pr #506 meant to resolve this issue? I'm currently trying to make it work but unfortunately Xcodegen doesn't automatically link.

@GRiMe2D that PR was more for single dependencies that come with multiple frameworks, not transitive Carthage dependencies
