🤩Apple Event Confirmed for September 10, 1:00-3:00 AM Taiwan Time
Apple's fall event time is confirmed! Expected to unveil the new generation iPhone, Apple Watch, and other products. The tagline is Awe Dropping. Will there be something amazing?
The preview page's logo creates an effect similar to thermal imaging, which you can interact with using your cursor or touch - go give it a try! After developers reverse-engineered it, they found it was made using Three.js shaders.
🧪Apple Releases
Xcode 26 beta 7 is now available. As previewed last week, this version supports Claude Sonnet 4. Rudrank Riyam, familiar with various AI development tools, shared his experience
🎨The Design Story Behind Xcode Diff View's Purple-Orange Color Scheme
Former Apple designer Edward Sanchez personally explained the design origins of the purple and orange color scheme in Xcode's diff view.
👀Apple FastVLM Models Land on Hugging Face
Apple has released three versions of FastVLM real-time vision-language models - 0.5B, 1.5B, and 7B - supporting WebGPU:
We introduce FastViTHD, a novel hybrid vision encoder designed to output fewer tokens and significantly reduce encoding time for high-resolution images.
Our smallest variant outperforms LLaVA-OneVision-0.5B with 85x faster Time-to-First-Token (TTFT) and 3.4x smaller vision encoder.
Our larger variants using Qwen2-7B LLM outperform recent works like Cambrian-1-8B while using a single image encoder with a 7.9x faster TTFT.
There's a WebGPU demo site that supports browser display (Safari not supported)
📚New Tool to Solve Apple Documentation AI Reading Issues
Apple's JS-rendered documentation prevents AI tools from reading correctly. Mattt created sosumi.ai. Simply replace developer.apple.com in the documentation URL with sosumi.ai to get clean, AI-readable Markdown format.
Another alternative is Peter Steinberger's llm.codes.
