You're having performance issues with SwiftUI and you're struggling to solve them? 😫
So did Airbnb and they've just published the method that solved them!
Let me walk you through it 😌
Published a new blog post about SwiftUI performance & tools we’re using at Airbnb to improve performance at scale medium.com/airbnb-engineerin…
Just published SwiftFormat 0.56.0 — it includes over a dozen new rules and options added by the community! github.com/nicklockwood/Swif…
Great writeup from Anne about the new Host Passport animations in Airbnb's iOS app!
How Airbnb enabled hosts and guests to connect and introduce themselves through the Host Passport.

Today, Boom announced the successful flight of XB-1, the world's first independently developed supersonic jet, at the Mojave Air & Space Port in Mojave, California. Flown by Chief Test Pilot Bill "Doc" Shoemaker, XB-1's inaugural flight marks a major milestone toward the return of supersonic travel onboard Overture - Boom's supersonic airliner. The XB-1 program provides the foundation for the design and development of Overture, while establishing a safety-first culture in engineering and manufacturing.
"Today, XB-1 took flight in the same hallowed airspace where the Bell X-1 first broke the sound barrier in 1947." said Blake Scholl, founder and CEO of Boom Supersonic. "I've been looking forward to this flight since founding Boom in 2014, and it marks the most significant milestone yet on our path to bring supersonic travel to passengers worldwide."

It's the clearest day California has had in weeks and the views are amazing.
A deep snowpack, green hills, and beautifully gushing rivers.

San Francsico may be getting a panda! 🐼
Multiple sources tell me SF and San Diego are the two cities vying for a giant panda from China. However, they believe SF has the edge given the city hosted APEC.
The mayor's press office confirms Mayor Breed has been speaking to the Chinese government for months before APEC to advocate for the pandas. She also asked directly while bidding President Xi Jinping farewell on the tarmac after APEC.
Breed also wrote a letter to President Xi dated 12/1/23, she proposed a partnership where the SF Zoo would host the "cherished diplomats". #SanFrancisco
