First Talk Description:
• Need for Speed: Building Suno iOS on Bazel
Sami Bouchebaba

This talk will cover how and why we moved Suno's iOS build and CI to Bazel, and the speed and reproducibility wins we got. We will then demo what we built on top of that foundation, including AI-powered autofixers that open PRs for codemods, automated test failure attribution and a skills-based agent system that is reshaping our dev workflow. Useful for any iOS team weighing Bazel, or thinking about where mobile DX is heading in the AI era.

Sami is an iOS engineer at Suno (previously Spotify and SoundCloud) who has spent the last decade shipping consumer features and building the tools that make shipping them easier. Equal parts product engineer and platform engineer with a soft spot for delightful developer tooling.

Second Talk Description:
• Swift Concurrency and Its Common (and Less Common) Gotchas
Winston Du

Swift’s structured concurrency feature introduced a new way to write parallel and asynchronous code — combining async/await syntax with compile-time checking for isolation and data-race safety. However, writing correct structured concurrency code is still easy to get wrong. In this talk, we’ll cover the core mental models behind Swift concurrency, common mistakes made and misconceptions, and a few less obvious edge cases you may run into in production. We’ll also look at how evolving language rules and legacy framework integration can create surprising behavior, even for experienced Swift developers.

Winston has been an iOS developer for over 6 years. He worked on the Backbone iOS app, messaging encryption at Meta for Messenger, the Liquid crypto trading app, and most recently the Pika "AI self" iOS app.
