Is the forEachGesture modifier not completely implemented currently? I’m trying to convert a simple drawing feature to iOS Compose (already have the Android version), but it seems like pressed is always set to false, which messes up the press/drag/release cycle. The lower-level parts of Compose have typically worked well, and it seems like this would have to work for the higher level UI elements to work properly.

Yes, for now it's not fully implemented yet. As multi touch and gestures too.

In that case, I’ll just leave my changes on a branch until it’s implemented in compose-jb. Where is touch gesture support in terms of priority? I see that UIKit interop was just drafted.

[Dima Avdeev]

UIKit interop and gestures have the same priority.
But, UIKit interop is a big feature and may take a long time to implement.
I think, gestures will be implemented by another developer. And maybe earlier.

I’d imagine UIKit interop will be quite the task, but it would be very helpful once done.

I looked over the draft a little bit. I noticed that y’all went the route of hybrid composition, as opposed to drawing the UIViews directly into the canvas, like on Android. Was there a blocker to drawing directly into the Canvas (I remember when I tried, I couldn’t easily get a redraw trigger working).

We have a draft that already works without Canvas. UIKit view draws in concrete rectangle. But this approach has visual problems.
For now, I am researching how to render UIKit widgets right in to Metal texture near Compose nodes.
