Apple released yet another beta build of its operating systems today, and this time there's something for everyone. Beta 6 of iOS 10, tvOS 10, and watchOS 3 was seeded to developers, as well as Public Beta 5 of iOS.
The news comes just six days after Developer Beta 5 and Public Beta 4; however, last Tuesday, the Public Beta was released later in the day. Clearly, Apple is getting more confident in its betas as the Developer and Public builds get closer together.
There is currently no new macOS 10.12 Sierra build available; however, the Apple Developer center also hasn't been updated to reflect the new betas. This means that we also don't yet have a new Xcode 8 beta, and no release notes, which means that we currently don't have any way to tell what's been fixed and what's still broken.
You can likely expect new betas for both macOS 10.12 Sierra (including a Public Beta) and Xcode 8 later today. For every beta round this summer, macOS has come later than the others, and Xcode 8 comes when Apple decides to update Apple Developer, which the company has really been taking its time with.
