Is this symbol, which Safari uses to the left of the address bar, in the public SF Symbols set? What's it called?
What's this SF Symbol, from Safari?
It seems like it might not be a public SF Symbol! D:
Judging by it's shape, the official symbol would likely be text.below.rectangle but sadly that symbol does not yet exist to my knowledge. I scrolled trough the entire catalogue and couldn't find it.
Though you're not out of luck!! Apple supports Custom Symbols! You can easily take elements from both text.below.photo and list.bullet.below.rectangle and combine them to create a custom symbol to use for your UI!
Apple has a video on how to do so. https://developer.apple.com/videos/play/wwdc2021/10250/
I hope this helps! And best of luck!
Thanks for checking!
