Whenever I present “Friendly Meals”, the AI-powered meal planner we built to demonstrate Firebase AI Logic, people will ask “did you ever try cooking those recipes?” This got us thinking…. Ladies and Gentlemen - may I present: youtu.be/yGekRAvAxPg...

Firebase now has SQL! Join me and my favourite co-host, @nohe.dev, on today's Firebase After Hours livestream. Our guests are Denver and Aashish, who work on Firebase Data Connect - we will chat with them about the Kotlin SDK! www.youtube.com/watch?v=EwY...

At DevFest Bletchley Park, someone asked "what happens if you ask the model to generate recipes that don't make sense". We all assumed the model would try to generate *something*, but today I learned that's not the case. Well, here you go - sometimes the model *does* push back:

Miked up and hyped up for my keynote "Machines Can't Think. Guiding Agents from Hallucination to Working Code" at DevFest Bletchley Park, hosted by The National Museum of Computing.

Xcode 26 now has built-in support for flashing updated regions in your SwiftUI apps. This helps you see which views are being redrawn. Note that this only works when running your app on a physical device. x.com/alpennec/st...

One of the things I love about @swiftleeds.co.uk: the attention to detail. This is one of the nicest conference badges I've ever gotten.

Great slides, much attention to detail, @chriswu.com !

I know I should be working on my slides for @swiftleeds.co.uk, but this weather is just too good to be true.

I'll just leave this here:

Apple's new SwiftUI WebView is slick! 🔥 But how do you use it without dropping support for older iOS versions? I just streamed how to build a backwards-compatible wrapper that uses the new WebView and falls back to WKWebView. Check out the recording: www.youtube.com/watch?v=OlH...

PSA: Gemini 1.5 models are fast approaching their retirement date (September 24th). This means any apps using these models will get 404 errors. You should update to newer models to avoid service disruption. We generally recommend using Remote Config... firebase.google.com/docs/ai-log...

When working with the Gemini CLI, I found it's a good idea to let the agent discover your project first so it understands the structure of the project and what it is about.

I recently upgraded one of my projects from the Gemini Developer API to the Vertex AI Gemini API, and ran into an issue saying "Requests to this API firebasevertexai.googleapis.com ... are blocked." Turns out, a couple of permissions were missing on my API key.
