It is best to wait to get a new update iOS9 or downgrade to iOS 8.4 ? (sorry for my bad english) 🙂
iOS 9 & Apple Music
got the same problem here. i want apple music but i dont want to downgrade.. but i am able to get it on my mac with os x El Capitan so that makes me a little happier
Maybe it has something to do with the simple fact that the "iPhone" is an evolution of the "iPod"... a ... wait for it.... MUSIC product. LOL
Not to mention all the interconnected UI components with the music player. The point isn't to have access to stuff to play with but to test against code that will be pushed to production. Apple is still doing quite a bit in a vacuum but it's getting past the point of necessity.
They already announced Apple Music and what it would, could and should do back at WWDC. No sense in holding it back for release as part of the standard beta build process. Except for the fact that Apple's dev teams are strained (apparently) and they have completely different branches being developed concurrently (often duplicating functionality) only to merge it later in the release cycle.
iOS 8.4 and iOS 9 concurrent beta releases is a perfect example of this.
Frankly, the Mac OS dev team has been far, far more consistent with their development efforts and I wouldn't be surprised to see iOS and Mac OS dev teams merged at some point in the future. (Things are already slowly moving in that direction with all the UI changes to Mac OS)
If you are trying to test an app that somehow integrates with Apple Music, and need to test something that will be released in the next week then clearly you are talking about an iOS 8.4 compatible app, not an iOS 9 one, since iOS 9 won't be out for months. Otherwise, you'll be able to test it on iOS 9 when the next beta comes out, probably.
The truth is, there is no logical argument for a dev *needing* Apple Music on their iOS 9-installed phone today. We may want it, but we want it as consumers and people who appreciate what Apple does.
Note too you can get Beats 1 via the current Music app in iOS 9. So you're not even missing the entire experience.
