Hello, anybody using compose iOS in production? How is the performance like?

Sounds like in 1.3 there was a pretty big performance bump. Check the post from Jan 3rd above.

Looks like interop is being worked on, but no timeline for completion.

where do you see that?

Honestly, I'd be happy with being able to use a Compose View inside a UIKit project. I have some simple low-risk dialogs that I'd like to use Compose for.
