Less than a week after the last iOS 9.1 beta release, Apple has now released a fourth beta of iOS 9.1 to developers. iOS 9.1 appears to be primarily focused on adding developer-level support for features such as 3D Touch and Live Photos on the iPhone 6s and iPhone 6s Plus, with this latest beta focusing on fixing a number of issues from prior betas.
Registered iOS developers can download the iOS 9.1 beta from Apple’s Developer site; a public version of the beta will likely be following soon.
In addition, Apple has also released a third beta of tvOS for the new Apple TV, intended to allow developers to get a head start on Apple TV App Development prior to the public release of the new set-top box.
The tvOS beta is intended only for those developers who have already received a development kit for the new Apple TV, as it only runs on the not-yet-released model.
