I am implementing a Fairplay Streaming player on Safari.It needs to prefetch a set of keys from KSM before the playback. All the examples I came across implement AvContentKeySession api but it is available only in Swift and Objective-C(for ios). What is equivalent of AVContentKeySession API on MacOS/Safari? Is there a reference code available to implement such a functionality on MacOS/Safari?

    According to the docs it is available on macOS as well: https://developer.apple.com/documentation/avfoundation/avcontentkeysession – koen Sep 16 '20 at 19:56

Availability

Here is the availability list per OS, from the documentation:

iOS 10.3+ macOS 10.12.4+
Mac Catalyst 13.0+
tvOS 10.2+
watchOS 7.0+

That means it's available on macOS 10.12.4 and later.

Safari

Apple has an official example project for this (the next title), under the project you can find the FairPlay Streaming in Safari directory which includes an example for Safari.
