Apple plans to seed iOS 8.4 Golden Master (GM), which has historically been release candidate software, to registered developers today ahead of the Apple Music launch on June 30, reports BGR. iOS 9 beta 2 is also reportedly scheduled for release today, although it is possible that the release date is pushed back by one week to next Monday, June 29.
The iOS 8.4 GM will succeed iOS 8.4 beta 4 and will most likely be the final pre-release version before the software update is publicly released. Apple Music for iPhone, iPad and iPod touch requires iOS 8.4, so the update should be released for all users within the next eight days, with the new streaming music service built into the revamped stock Music app.
Apple Music was announced earlier this month as an all-in-one streaming music service, live global radio station and social platform for artists to connect with fans. The subscription-based service will cost $9.99 per month after a three-month free trial for iPhone, iPad, iPod touch, Mac and PC. Apple TV and Android versions of the service will be available in the fall.
Update: BGR's report proved inaccurate as Apple seeded iOS 9 beta 2 on Tuesday and has yet to release the iOS 8.4 GM.
