@BrandonButch Finally!

[Google for Developers @googledevs]

Gemini models are now accessible to millions of Apple developers through Apple’s Foundation Models framework and natively within Xcode. You can now easily swap between local and cloud inference using a shared API surface to build next-generation agentic app experiences, increase development velocity, and offload heavy workloads to the cloud. Additionally, you can use agentic coding assistance from Gemini in Xcode to accelerate multi-step development tasks.

Swift devs: if you’re interested in using Gemini in Apple’s Foundation Model API, come see our special guest @peterfriese (Google) and his team of engineers at the AiOS meetup in Cupertino this Thursday.
Besides Peter we have @awnihannun (co-creator MLX and now at Anthropic) for a special talk as well

@puf @Firebase I guess I can use this tweet to get approval for another trip to SFO when you're in town ;-)

@Firebase On my way to @communitykit_ for the #wwdc watch parties.

“I’m so excited” - love the Royal Republic cover, so fitting! Can’t wait :-)

@Firebase Getting some work done from inside the GooglePlex. It’s been a while since I’ve last been here…

[Peter Friese @peterfriese]

@puf @Firebase Haha - where is the edit button when you need it, right?

Here until Saturday!

Did you ever wonder why Apple introduced `contextSize`?

@DanielBerezhnoy Not unless someone magically pulls out a last minute ticket for me… I’ll be at the community events.

From a recent Decoder interview with Harvey Mason Jr. Musicians have been using AI (for example to extract stems) for a long time. Now’s it’s even more pervasive, and - just like in software engineering - it can free up time to work on what you really care about.

[Peter Friese @peterfriese]

Couldn’t agree more. I find it baffling that the general public opinion is “there is no longer a need for software engineers due to AI”. The opposite is true - you need people who can translate (business) requirements to code (by using AI) even more than before. There is no way how you could one-shot even moderately complex software at the moment. Engineers write skills, agent files, evals, etc., and they need to review code (or write review agents). As many times before, we’re elevating the level of abstraction we’re dealing with, that’s all.
