As expected, Apple has released the final “GM” versions of iOS 10, watchOS 3, and tvOS 10 to registered developers in advance of their final release, scheduled for Sept. 13.
Barring any significant problems, these final developer releases are normally identical to the versions that are ultimately released to the public, and are listed in the Software Updates scenes simply as the base versions (e.g. “iOS 10”) with full final release notes and no “beta” designation.
Notably, iOS 10 on Apple’s Developer Download Site is listed as “iOS 10.0.1” and includes a build number of 14A403. watchOS 3 has a build number of 14S326 and tvOS 10 is 14T330 — these numbers should be identical to the final versions released next week, so as usual, developers installing the GM seeds will not need to install the final public release.
