Want to try out watchOS 3 on your Watch? You’ll need iOS 10 on your iPhone. Dan Moren walks through all the steps to connect Apple’s OS’s.
Want to try out Apple’s new Auto Unlock feature? You’ll need to have the watchOS 3 beta installed and the macOS Sierra beta.

And the Universal Clipboard? Well, yeah, I think you can figure that out.
It’s all connected.
