Apple Releases iOS 14.5 Public Beta 4 for iPhone, Features Reference to New 'City Charts' Playlists in Apple Music

Apple released the fourth public beta for iPhone today, Monday, Mar. 15. The update (build number 18E5178a) comes three hours after the fourth 14.5 developer beta, and includes references in its code to a new "City Charts" playlist feature in Apple Music.

This new playlist feature takes the most popular songs from different parts of the world and puts them into individual playlists. It's a cool idea, but it's impossible to say how long until we'll see it in action. Apple didn't include any user-facing aspect of City Charts into beta 4. As outlined by 9to5Mac, Apple includes references to the feature in beta 4's code only.

Apple's release notes are short, but they mention a known issue with Handoff where you might not able to transfer audio to your Homepod. The company says use playback controls or Control Center rather than Handoff until the issue is fixed in a subsequent update.
