Custom Share Destination
You can receive rendered media (movies), editing descriptions for project timelines, library archives, and FCPXML for other Final Cut Pro items in your app.
You can read Apple's official documentation here.
Unfortunately the documentation is fairly complex, and there's no good sample code to get started quickly.
It is especially very confusing if you're a Swift / Swift UI developer, with no experience in Objective-C.
However, I've uploaded a old sample project from Apple to GitHub, along with an attempt to "wrap" the Objective-C code in a Swift application.
You can find ShareDestinationKit on GitHub here.
