Thanks for this PR.

Can you elaborate on the use case a bit maybe? What kind of plugins need this? Example?

I can't share a concrete example but I'm developing a plugin for my company and this feature is required. I think it can be useful for future plugins developed with swift and need a minimum version of iOS.
