问题
I can't find latest watchOS 3 SDK inside latest version of XCode 8 beta 2 even though they have mentioned it in their release notes. I have upgraded my Apple Watch to watchOS 3 beta 2 but I can't run my app on it:
Error: No symbols for paired Apple Watch

It's available in the latest XCode version 8.2. Download it from the apple website.
