iOS 8.4 beta 4

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 are the iOS 8.4 beta 4 release notes:

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 as button.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.

    Curious if this has the same “Music” app that is seen in iOS 9 Beta 1?

    • The Music apps in iOS 8.4 beta 1-3 and 9.0 beta 1 appear to be very similar (I haven’t spotted a difference), so 8.4 beta 4 is likely the same as well.

      • Rodney Coleman

        I would think so

    • Quang

      yup it seems to be the same, at least the new UI

  • Wilberth Barrantes

    There’s also an update for public beta

    • Rodney Coleman

      Don’t know why yall don’t pay $5 and get your UDID registered to get official beta.

      • Dany Quirion

        public beta is the exact same lol

      • Chris

        The public BETA is slightly different than the developer BETA releases, in some cases what the public gets can contain less changes than what the developer release had.

    • Sebastian Solaeche

      how can I get these public beta updates?

  • Preben Faarkrog Hansen

    • Мирас Мынжасар

    • Ángel Javier Esquivel

      You don’t need registration, at least for this beta 1

  • Rupinder

    I want Apple Music so badly.

    • Rodney Coleman

      Update to iOS 8.4 it’s worth it.

      • Tony Trenkle Jr.

        Its not out yet…comes out on the 30th…

      • Rupinder

        It doesn’t include Apple Music, sadly.

    • Byron C Mayes

      Only three more weeks. But it does have the new Music app UI.

  • Byron C Mayes

    Public Beta 3 is also out.

  • Brian

    Can someone PLEASE tell me how to get into the iOS Public Beta? I follow the directions and I’m part of the OSX Public Beta but I never see an option to get iOS. I signed up early too. Any suggestions?

    • Mustang5Oh

      The iOS public beta was invite only. However, there is a profile you can download on your phone that makes the public beta appear under software update in the settings app.

      • Brian

        At the risk of being THAT guy, can you give me any info on getting that profile?

  • yzjustdatguy

    That effective power glitch was also patched
