You know that feeling you get after WWDC ends, when all you want to do is catch up on all the videos Apple just released? That urgent need to experiment and play with all the new betas, frameworks and APIs. The overwhelming desire to spend hours on all of the above, quickly followed by the sinking realization that you can't - because you have actual work to do. Yep, we've all been there and that feeling sucks. Swift Island is an all-inclusive experimental conference happening in September 2025. This is the official companion app for Swift Island.
