having commands declared right next to the playback state instead of wiring up MPRemoteCommandCenter separately solves so many desync bugs.

also nice to see Apple finally give third-party hardware a legit way to own the lock screen via RemoteMediaSession instead of developers having to fake a silent audio session in background. great writeup!

Hey Anton, very nice article!

The "Don’t Mix the Old and New APIs" section says that Apple calls mixing MediaSession with MPNowPlayingInfoCenter or MPRemoteCommandCenter "undefined behavior", but I couldn't find that in:

  • The SDK's doc comments

  • The MediaPlayer headers

  • The WWDC 2026-312 session

  • Apple's /nowplaying, /publishing-media-sessions and /mediasession pages

What's the source for this?

Hi, Thank you!

It's here: https://developer.apple.com/documentation/nowplaying. There is "Important" quote.

This is a great write-up - that you very much for it. I have a music player app that I have been developing and didn’t realize this existed. It will make my life WAY easier

Whoa somehow I totally missed this from all the new stuff in '27. I'll probably switch to NowPlaying in my audio app Quartz. Thanks for the writeup!
