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

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

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


We re-evaluated our previous decision to disable changing the playback rate of subscription content from Apple Music in third-party apps, and came to the conclusion that we can safely enable this functionality again, just as it was before iOS 15.4.

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

Hope this helps.

Best regards,

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