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.
Dr. Drang is the pseudonymous engineer behind 'And now it's all this,' the long-running blog at leancrew.com where he posts small, fully-explained scripts that bend macOS to his will. By day he is a practicing civil and mechanical engineer with a Ph.D. in stress and structural analysis; by night he writes Python in BBEdit, glues apps together with AppleScript and Shortcuts, and walks readers through every line of code. His pen name is an engineering in-joke - 'Drang' is German for stress - and he has guarded his anonymity for over two decades to keep his consulting clients from finding his musings on math, music, and Mac automation.
Dr Howard Oakley is the one-man newsroom and software workshop behind The Eclectic Light Company, a blog that pairs deep-dive macOS internals with the history of painting. A retired Royal Navy Surgeon Commander and cold-injury researcher turned indie Mac developer, he writes daily about how macOS actually works and ships more than 40 free utilities such as SilentKnight, Consolation and T2M2 - all without a single line of AI-generated content.
Michael Tsai is an indie Mac developer and the one-person operation behind C-Command Software, creator of SpamSieve - the gold-standard Bayesian spam filter for macOS that has been filtering email since 2002. He also runs one of the most respected daily link blogs in the Apple developer community, curating Mac and iOS developer news with original commentary since 2002. His roundups of community reaction to Apple events are so authoritative that Daring Fireball's John Gruber regularly links to them as the definitive overview.
Paul Hudson is a British Swift developer, author, and educator based in Bath, England, best known as the creator of Hacking with Swift - the world's largest Swift tutorial site. With over 700,000 unique monthly visitors, 20+ books, and free courses like 100 Days of SwiftUI, he has taught hundreds of thousands of developers how to build iOS apps. A former tech journalist at Future Publishing, he invented FutureFolio for iPad publishing, then pivoted to become the go-to teacher for the Swift community - co-hosting the Swift over Coffee podcast, maintaining popular open-source projects like ControlRoom and Ignite, and raising over $40,000 for Black Girls Code through the Swift for Good charity anthology.
Simon Støvring is a Danish indie iOS developer and principal iOS engineer at Framna, best known for creating Scriptable — the app that lets anyone automate their iPhone with JavaScript. By day he architects mobile apps for a Nordic agency; by night he ships beloved tools like Runestone (a Tree-sitter-powered text editor), Data Jar, and Jayson. His work sits at the intersection of power-user utility and delightful craftsmanship, earning him a loyal following among iOS enthusiasts, automation nerds, and developers worldwide.
Stephen Hackett is a Memphis-based writer, podcaster, and co-founder of Relay FM - one of the most respected independent podcast networks in the Apple world. Through his blog 512 Pixels (running since 2008), his flagship podcast Connected, and co-hosting Mac Power Users, he has built a career at the intersection of Apple history, hardware archaeology, and independent publishing. He is also the driving force behind Relay FM's annual St. Jude Children's Research Hospital fundraiser, which has raised nearly $5 million - a cause deeply personal to him after his son Josiah survived pediatric brain cancer treated at St. Jude.
