Honestly, this doesn’t make sense. Seems arrogant and uninformed. Regardless of how good of a product person they are, everyone should be receptive of feedback and aware of how others are trying to tackle the same problem

Now, we're the first to release a tool to allow anyone to generate symbols for any framework, which means no more obfuscated crash reports 🤯
Stoked to end the year with a 💥

This is just an incredible feat by our team. The first time anyone outside of

has been able to symbolicate
#SwiftUI
You may have noticed SwiftUI doesn't display function names in a crash report, making it almost useless 🤕
But we've discovered how to symbolicate SwiftUI 🔬
Here we detail how it's done + how to symbolicate any framework w/out symbols

👁️ Day 1 Vision Pro scattered first impressions (including a couple hot takes):
- The setup is a bit clunky, my eyes definitely had trouble getting adjusted. Eye and hand tracking still leave some room for improvement.
