I can’t make it to San Francisco for WWDC, but if you’re going to be in town, you should definitely go to Layers, from Jessie Char and Elaine Pow. Just look at the lineup, and their rad ticket pricing policy:
If you’re a woman by birth or identity, use the code #ragegap to receive a Layers pass for 77 cents on the dollar.
Ever since WWDC tickets have been delivered Willy Wonka style, there have been a few great conferences that have sprung up to accommodate the overflow. If Layers’ designer focus isn’t so much your speed, check out AltConf as well. I wish I could go to Layers, though — it looks absolutely incredible.
