Inspired by @tomekzaw_'s Android <𝚃𝚎𝚡𝚝> profiling thread, I dug into the iOS side: how <𝚃𝚎𝚡𝚝> is measured and drawn, and what the <𝚅𝚒𝚎𝚠>s around it do when they move or fade ⏱️ Benchmarked with Argent on a physical iPhone 📱 So far, 4 PRs 🧵

Great article from @incident_io on testing apps in the cloud with agents. Nice insights and explanations on tunneling simulator access from a lightweight VM. Powered by @agent_device and @expo infrastructure!

We've just released a new official Android skill that can be used to statically analyse your #JetpackCompose code for performance improvements. ⚡️ Install it, and ask your agent to run the skill on your code. 🧑‍💻 We've seen some good results running it internally - give it a try and let us know any feedback! github.com/android/skills/tr…
