What I'm working on
Conference Talk Preparation win-win's
Tomorrow, I'll be flying towards Bologna to speak at #Pragma Conference 2025. I'll be giving a talk on a topic that I've invested in a lot lately: Swift 6.2 is here — It’s time to migrate to Strict Concurrency.
I've been giving many talks over the years, and I have a clear process for each:
Open up notes, solely focusing on the structure of the talk Start a new Keynote file using the SwiftLee template Work through all slides and target the ~30 minutes total time
Just before I go on stage, I always read my own tips from over the years: Presentation tips for performing professional Swift talks (I'm still updating this after each conference based on new insights). It's these processes that make talk preparations more efficient.
Since recently, I also started taking YouTube more seriously (subscribe here). This means I'm looking different at my talks now:
I want the talk to be convertible into multiple smaller videos The complete talk will be recorded on my channel after the conferences Shorts will be used across socials
These all make sense if you think about it — it's a clear win-win. I focus on the slides once, I prepare my talk by recording the videos, and I end up with high-quality content for my YouTube channel while also performing a conference talk.
Win-wins like these made me a successful creator, it's an identity that I don't let go.
Finally, I was going to promote my Going Indie course — but instead, I’ve got something even better.
