What high level APIs are you referring to?

I don’t know; I am not a mobile developer. I’d imagine there are plenty of cool things you can do with API exposed by Apple in Swift constructs?
I was playing as the devil advocate here. I understand that everything you can do with Swift you can do with Elixir but in the Swift case I have a first party maintained high level wrapper but in the second case I will need to do some unpleasant plumbing with NIF and C API, which may fell out at the next update.

I’m planning on using SwiftUI which is the same thing LVN is using.
On the Android side I think Java and Kotlin are mapping to the same underlying view tree.
I don’t think there is any other higher constructs to target and still call it native.

NxIREE can run on iOS (I even got it bundled with LiveView Native apps), and for iOS specifically we can also try to get EMLX running!
Surely for Android we could try NxEigen, EXLA or a future OpenCL compiler. So I definitely am interested in exploring this further

@derek-zhou there are ways of calling Swift code from C and C from Swift. In this project I have a few examples for the latter code-beam-lite-nyc-2024/beamstagram/native/swiftui/Beamstagram at 616324a03685ee481d00e131ab47923b5b027de6 · polvalente/code-beam-lite-nyc-2024 · GitHub
I think a similar approach could be taken to call Swift from C, and then just the common types would have to be registered on both sides.

Interested. I really like the way of working with tensors in Nx. I hope we can use that on mobile soon!

@polvalente @manhvu what would you want to do with Nx on mobile? I hadn’t really considered this until now but it would be cool to get something working.

Apple has pretty cool MLX examples. Also, running YOLO models or something like that on-device would be cool.

My bad here. On Android there is Jetpack Compose and on iOS side it’s SwiftUI so I will be using those.

I think when experimenting with elixir-desktop a few years ago I found running the BEAM on iOS used excessive battery. I’m not sure if that is a problem anymore but I assume for your native purpose you can’t somehow use Popcorn/AtomVM and compile everything to wasm then bridge to native? I will say I’ve compiled and profiled GitHub - u9g/uno-royale · GitHub which runs LiveView fully offline on device (through a Swift webview) and it works great with minimal battery impact. I know the full BEAM is not implemented but enough of it is to enable this app to work great.
