iOS 15.5 to Reintroduce Apple Music API Used by Third-Party Apps to Adjust Playback Speed

iOS 15.5 will include the reintroduction of a popular Apple Music API used by third-party music players that allowed users to change the playback speeds of songs within the app, an Apple software engineer has announced.

iOS 15
With iOS 15.4, Apple removed an API used by third-party Apple Music players that let users change the playback speed of songs. The ‌Apple Music‌ app itself does not let users change playback speed, but popular App Store apps like Perfect Tempo offer users that ability. For some unknown reason, Apple removed the API with iOS 15.4 but with the upcoming release of iOS 15.5, currently in testing, Apple is adding back the functionality.

Joe Kun, an Apple software engineer on the ‌Apple Music‌ team, posted this update to frustrated developers earlier this week (via iGeneration):

Hello,

We have re-evaluated our previous decision to disable changing the playback rate for subscription content from Apple Music in third-party applications, and we came to the conclusion that we could safely enable that functionality again, just like before the release of iOS 15.4.

As such, this issue is fixed in iOS 15.5 beta 4.

I hope this helps.

Best regards,

Apple this week released the fourth beta of iOS and iPadOS 15.5 to developers. iOS 15.5 will include only small changes and features, alongside performance and security fixes. You can find all the changes coming with iOS and iPadOS 15.5 here.

Apple today sent out invites for an experience in Los Angeles on Wednesday, October 28, and the "Pro and tell" tagline on the invitation likely means that the rumored MacBook models with touch-enabled OLED displays will stick with MacBook Pro branding instead of the once-rumored "MacBook Ultra" name. The long-rumored "iPhone Ultra" ended up being named iPhone Duo, so speculation that Apple...

Good news: We're putting back the API to let third-party apps control the tempo in Apple Music.

Bad news: We're bumping your app off the dock to make room for Apple Music 🤪

Good move by Apple to put it back. I'm very surprised they are backtracking on this decision.
