appClipActivationPayload missing in Objective C?

I'm hoping to add an App Clip to an app written in Objective C.

I can get the NSUserActivity object from options in
Code Block
willConnectToSession:(UISceneSession *)session
options:(UISceneConnectionOptions *)connectionOptions

but the appClipActivationPayload doesn't seem to be a part of the Objective C library yet. Is that true, and do you know when it will be available?

Thanks!
Should add that I'm using Xcode Version 12.0 beta (12A6159).
For anyone else who has this problem in Objective C, I found I needed to do two things:
  1. Add "#import <AppClip/NSUserActivity+AppClip.h> to your header file.

  2. Add "AppClip.framework" under your App Clip target's General / Frameworks, Libraries, and Embedded Content.

#1 will allow it compile, but the appClipActivationPayload attribute won't be there in runtime.
#2 will prevent the crash when you try to access the appClipActivationPayload attribute.
