Apple has released its third beta of iOS 8.4 to developers, continuing to focus on the new iOS Music app. Featuring a build number of 12H4098c, the release is also accompanied by a new Xcode 6.4 beta to support the new APIs and development environment. The release notes for this latest beta indicate both improvements and limitations in App Extensions, the iTunes Store, Siri, Videos, and WatchKit, as well as with the new Music app. The new Music app appears to continue having a long list of issues that remain to be addressed, with limited progress since the first beta, although the language of several has been softened from phrases such as “does not work” to “may not work” suggesting that Apple is perhaps slowly working on improvements in these areas.
