On Tuesday, Apple released new developer betas of iOS 8.4 and OS X 10.10.4, the next updates for the current versions of iOS and OS X. As with previous releases, the new betas focus on bug fixes and other enhancements for each of the two platforms, while the iOS beta continues to feature the preliminary Apple Music application, which will replace the current Music app but continue its functions with a revamped UI that also includes an optional subscription component. In addition, the company has released its first beta of Xcode 7.
