Now Playing Integration Guide

Purpose: Prevent the 4 most common Now Playing issues on iOS 18+: info not appearing, commands not working, artwork problems, and state sync issues

Swift Version: Swift 6.0+ iOS Version: iOS 18+ Xcode: Xcode 16+

Core Philosophy

"Now Playing eligibility requires THREE things working together: AVAudioSession activation, remote command handlers, and metadata publishing. Missing ANY of these silently breaks the entire system. 90% of Now Playing issues stem from incorrect activation order or missing command handlers, not API bugs."

Key Insight from WWDC 2022/110338: Apps must meet two system heuristics:

1. Register handlers for at least one remote command
2. Configure AVAudioSession with a non-mixable category
