What I'm working on
Back into business
After two great weeks of holidays, it’s time to get back into business. Here’s what you can expect in the upcoming weeks:
The release of the first few modules for my new AI Fundamentals course A first introduction to a new addition to the Rocket family. Yes, we’re going to release a new app that starts with "Rocket" in the name! A major update to RocketSim, with enhanced support for physical devices and more CLI functionality.
The WWDC releases are still fresh, and I’m excited to dive into adding support for new APIs. While I’m sure you know what’s new in SwiftUI or Swift Concurrency, you might not know about the new possibilities that exist for Simulators and Devices. I’ll take responsibility for just building what you need!
RocketSim’s CLI has been embraced by many existing customers, but I’m also working with a few enterprise companies that are considering using it. This requires me to apply a few important improvements that will ship over the coming weeks.
I realize I’m teasing a lot here, but it’s day 1 post-holiday, so bear with me. Stay tuned for exciting updates.
