Beta 2 Available, Limited Documented Fixes
/You can go and grab Beta 2 now, it's good to see many of the issues now listed in known issues, but not a lot in fixes. One highlight in the Swift known issues list, right at the top, is that public/private accessors are "not available in this build". Nicely implies they are on their way though!
What is good is a decent set of work-arounds for many known issues.
