Before Swift was open sourced, our only way to communicate with Apple was through Radar. Filing Radars is an arcane, opaque, and frequently frustrating process. But now we have a whole host of ways to chat directly to Apple engineers, all the way from mailing lists to Twitter messages. Even better than that we can actually dig through large bits of the code we use every day, and see how it works. And then when we find something we think could be better we can fix it! Thats exactly what I did, and last summer a small piece of my code shipped with Xcode 8, and most of you have probably used it. In this talk I’ll tell the story of exactly how that came to be, and explore ways that you can get involved too.
