Re: Speaking at Bletchley Park, Liquid Glass compatibility, and iOS 26 approaches

Hey everyone!

I’m in the middle of preparing a trip to the UK: first, I’ll be in London for a couple of days to help staff Cloud Summit London. After that, I will be at the Build with AI event @ Bletchley Park. This event will be held at The National Museum of Computing, and I’ve been told that one of the conference stages will be in front of the oldes working computer worldwide - super exciting! I’ve got the honor to deliver part of the keynote, together with Gus Martins and Rosário Fernandez - it should be fun! Final tickets are available here.

If you happen to see me, to say hi - it’s lovely meeting people in real live that you typically only “see” online!

The week after, I’ll be back in London, to record a couple of videos about Firebase AI Logic at the Google office near King’s Cross station - keep your eyes peeled on the Firebase YouTube channel (don’t forget to subscribe to be notified when they land)!

In this issue, I’ve included a couple of links that cover the new Liquid Glass design in your apps, while keeping them backward compatible, something that I will also look into in my next livestream. There are a couple of different approaches, each with different advantages and drawbacks. I like Majid’s approach that includes a clever way of making sure you clean up any obsolete code once you start shipping to iOS 26.

See you around, online or IRL!

Cheers, Peter
