Specifying SPM lockfile during generation

[jurvis]

Hi, I was wondering if it is possible to specify a Package.resolved to be used instead of defining packages individually in the yml file? A plausible use-case here would be to lock in a specific transitive dependency's version instead of having it potentially resolve to a later version when one is available.

Thanks!

maybe a reasonable workaround is to identify the transitive dependency and define it explicitly in the project.yml file for XcodeGen? would that work?
