Apple seeds iOS 8.4 beta 4 to developers

Apple seeded iOS 8.4 beta 4 to developers this afternoon. It is available immediately to those developers running iOS 8.4 beta 3 via Settings → General → Software Update. It is also now available as a download from Apple’s redesigned Developer Portal.

The iOS 8.4 beta 4 release, which is build 12H4125a, comes nearly a month after iOS 8.4 beta 3. Apple announced at yesterday’s WWDC keynote, that its new Apple Music streaming service was set to debut on June 30th. This means that we’ll see the final version of iOS 8.4, in which Apple Music will officially arrive to the public, before the end of the month.

Here's what's new:

App Extensions

  • App extensions need an arm64 slice to run on 64-bit devices. If you try to run the armv7 slice on a 64-bit device it won’t work.
  • Apps need to have an arm64 slice if the bundle contains a framework that both the app and the app extension link against.


Fixed in Beta 4
  • Using Siri to control iTunes Radio does not work in this beta.
Known Issues
  • Home Sharing and Genius Mixes are not currently available.
  • AirPlay streaming may not work.
  • It’s not possible to start a station from a song or artist.
  • Station sharing for iTunes Radio is not available.
  • The iTunes Radio tab may unexpectedly appear within Search, even if iTunes Radio is not available in your country.
  • The Music app may forget its place when you go to the Home screen and come back.
  • Ads in iTunes Radio may display on top of Up Next.
  • The downloaded icon is not displayed in Songs view on the iPad when you select “Make Available Offline.”


Known Issue
  • “Play <Song> Siri” requests from a watch are failing for a few days when the iPhone has a new install of iOS 8.4. Workaround: Request playback of Artists or Albums instead of a specific song.


When linking against iOS 8.3 or later, any code that relies on layout information (such as the frame) of a UIButton subview when the button is not in the window hierarchy will need to send layoutIfNeeded to the button before retrieving layout information (such asbutton.titleLabel.frame) to ensure that the layout values are up to date.


Known Issues
  • Content stored in iCloud may not appear in your library after signing in.


A bug where continuous background location updates fail to update has been resolved. If your Watch app relies on continuous background location updates to function, it is recommended that you update your WatchKit extension deployment target to iOS 8.3 and submit your app with Xcode 6.3.
