So the new SharePlay on iOS 15 works by utilizing GroupActivities which are only available in Swift. My existing app has a fairly extensive bit of code for viewing videos, but that code is all Objective-C.
If I want to get SharePlay to work with this app, am I going to have to convert all that to Swift, or is it possible to pass the AVPlayer stuff back and forth?
Can GroupActivity be in its own class and receive the data from the Objective-C file that parses the video file in question?
