Developers can now get their hands on the third beta version of watchOS 3. The configuration file is available from the Apple Developer Download site, while the update itself can be downloaded and installed from an iPhone running the latest beta of iOS 10.

Developers can now get their hands on watchOS 3 beta 2

When it arrives for the Apple Watch this fall, watchOS 3 will focus on major enhancements to speed, particularly for launching apps. People will now be able to keep a number of apps in the new watch dock for easy access and quick launching. Apps will also be able to fetch background updates.

How to download the watchOS 3 beta for developers

Apple occasionally offers updates to iOS, watchOS, tvOS, and macOS as closed developer previews or public betas for iPhone, iPad, Apple TV and Mac (sadly, no public beta for the Apple Watch). While the betas contain new features, they also contain pre-release bugs that can prevent the normal use of your iPhone, iPad, Apple Watch, Apple TV, or Mac, and are not intended for everyday use on a primary device. That's why we strongly recommend staying away from developer previews unless you need them for software development, and using the public betas with caution. If you depend on your devices, wait for the final release.
