The output of the Kotlin compiler is truly naive, indistinguishable from a library written in Java/ObjectiveC on their respective platforms, you can directly call Android/iOS APIs.Which native iOS APIs does Compose for iOS use? UIKit? CoreGraphics? Some of both?

04/14/2023, 9:39 PMI've asked the same question today at the JetBrains booth at KotlinConf, and from how I understood it, it's all drawn on a canvas. So no native widgets under the hood

04/15/2023, 6:53 AMCompose uses UIKit:
UIView, UIViewController for display own canvas
And some another iOS API:
Like keyboard events, orientation events, etc.

04/15/2023, 6:55 AMBut most of the UI is drawn on canvas with Skia

04/15/2023, 8:47 AMOh really, no native controls?

Dima Avdeev
04/15/2023, 8:54 AMFor now - no native controls
Dima Avdeev
04/15/2023, 8:54 AMSkia uses Metal to draw primitives
Dima Avdeev
04/15/2023, 8:55 AMAnd we use Skia to draw all of UI elements

04/15/2023, 1:50 PMFor Native Components there will be Redwood. https://github.com/cashapp/redwood/
The talk at KotlinConf:
At some point I hope to see a Compose UI Multiplatform and Redwood interop (Redwood Compose UI Widget).

04/15/2023, 1:55 PMThanks, Redwood it is also very interesting product!
We are thinking about using Redwood inside our Compose Multiplatform with a simplified version of UIKitView (maybe RedwoodView) right inside Compose Multiplatform.
This approach can help to share the same State<T>
