Dave DeLong is a software craftsman with fifteen years of building iOS and macOS apps that ship on billions of devices - and, he likes to point out, some that run in outer space. A seven-year Apple veteran who worked on Siri, UIKit, Apple Maps, and Developer Evangelism, he led the WWDC app from 2013 to 2015 and helped ship the first releases of Swift, WatchKit, HomeKit, and HealthKit. He is among the top contributors of all time on Stack Overflow, a fixture of the Swift Evolution process, and the author of widely cited open-source libraries on calendrical math. He blogs at davedelong.com, speaks at conferences worldwide, and is currently building a stealth startup.
Kilo Loco is the alias of Kyle Lee, a self-taught iOS engineer, instructor, and content creator who turned a string of dead-end jobs into a nine-year career building production mobile apps. After teaching himself Swift to build apps for his own family, he became a Senior Developer Advocate at AWS Amplify, reached tens of thousands of developers through YouTube tutorials and courses, and now leads iOS work on accessibility testing tools at Deque Systems while tinkering at the edge of AI and developer tooling.
Natalia Panferova is a Swift developer, author, and co-founder of Nil Coalescing - a technical education company built on the premise that understanding why SwiftUI works the way it does beats memorizing what it does. A former Apple SwiftUI Frameworks Engineer who was recruited after Apple discovered her blog, she personally built APIs (AttributedString, Markdown in Text, sheet detents) now used by millions of iOS developers daily. She publishes books, a blog, and the Nilcoalescing newsletter from a small town in New Zealand's wine country.
