Jev doesn't hallucinate. Instead, it gives you a confidence level that you can grab from the response metadata, like this:

Jev is typesafe, so it's only natural to map Swift types directly to Jev decision primitives:

Want to use Typesafe's Jev in your Swift apps using the convenience of Apple's Foundation Models framework? Well - here you go (GitHub repo link in the replies)! (h/t to Richard Wei for the inspiration!)

The Firebase Apple SDK now supports AsyncStreams for Firestore snapshot listeners, realtime Remote Config, and Firebase Auth. To hear more about how we built this and the underlying principles, come to my talk "Don’t call us - we’ll call you: Modern SwiftUI callbacks using AsyncStream" at swiftCon!

Curious? Here's a sneak peek into the demo:

I love giving talks that have a fun demo. For this year at DevFest HAM, I will bring Sherlock Holmes back to life with Gemini TTS. Come join me on October 16th in Hamburg, it's going to be fun!

If you've received multiple copies of Not only Swift today... I'm so sorry 🫣 I added some automation steps to my newsletter engine a while ago, and by a combination of unlucky circumstances my script ended up pushing the newsletter not once or twice, but 5 times 😱

Xcode 27 beta 6 now has support for Antigravity!

I built a Gelato ordering app three different ways 1) Just using a simple prompt 2) Using the same prompt 3) A full blown PRD Needless to say, the version with the full PRD turned out best...

GelatoGo app displays various gelato flavors, featuring customization options and a mobile view.

Every Firebase project is a Google Cloud Project. Navigating to your GCP project from the Firebase console used to be difficult. No more! Go to Settings > General, then click on View in Google Cloud, and #boom! you're in your project on GCP. #thingsyoudidnotknowaboutfirebase

Firebase project settings display details like project name, ID, environment type, and a link to Google Cloud.

Google Cloud interface displaying project details, options to create resources, and a promotional message for the Developer Programme.

Had a chat with twostraws.bsky.social about generating images with Nano Banana using the Gemini Developer API. Here is one the images I had Nano Banana generate. Want to generate images in bulk? Check out the CLI I built. Link in the next post.

Did somebody say "Swift Language Guide as a PDF"? I created a Typist template for textbooks with wide margins, and as a way to test-drive it, I converted the Swift Language Guide - enjoy! If you find any mistakes, please open an issue on the repo. github.com/peterfriese...

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:

Source image and prompt. Prompt in ALT text.

First ask me to upload an image of my room and then create a detailed 3D illustration of a miniature, cozy workspace in a cube, based on the items in the picture. The perspective should be isometric, looking down into the room from a diagonal angle. The room should be filled with tiny, charming details that reflect a person's hobbies and personality. Include a wooden desk with a laptop, a comfortable chair, shelves with books and plants, and warm, soft lighting. The computer is a MacBook Pro. The chair is a Herman Miller Aeron. The keyboard is a Keychron K1 Pro Make sure to include the sofa you can see. Put some pictures of icon London skyline perspectives on the wall.

I always wanted to have one of those 3D isometric tiny room illustrations of my office. Nano Banana was able to create this super realistic version of my room (source photo in the first reply)

An isometric 3D illustration of a miniature, cozy workspace within a cube. The room is viewed from a diagonal top-down angle and features a wooden desk with a MacBook Pro, a Herman Miller Aeron chair, and a Keychron K1 Pro keyboard. A grey sofa rests against the back wall next to a bookshelf filled with books and plants. The walls are adorned with framed pictures of the London skyline, and the entire scene is bathed in warm, soft lighting, creating a charming and personalized atmosphere.
