All the cool kids are doing it, and so are we: starting Monday April 23rd, we’re holding a week long Swift hackathon! We will be focusing for a whole week on bugfixes, and at the end of that week release the first beta of Swift 2.0, the next major Swift release. Everyone is invited to join us online in our chatroom at email@example.com, and start hacking with us. And if you can’t or don’t want to fix bugs, we also need plenty of people to help us with testing Swift extensively that week.
(Thanks to Tobias for suggesting this).
