I'm looking for an easy way to get a androidx.compose.ui.graphics.painter.Painter for my SVG & bitmap resource images. For JVM we have loadXmlImageVector() and BitmapPainter , which are not available for Compose for iOS. I have them in a folder, but I wouldn't mind (for now) to further use the Assets.xcassets as SwiftUI requires me to.

I looked at https://github.com/Kotlin/kmm-production-sample/tree/compose-app which uses https://github.com/Skeptick/libres to do that, but this unfortunately requires CocoaPods, which I don't want in my project setup.

What are other options to use SVG & Bitmaps for my Icons with Compose for iOS?

[Stefan Oltmann]

The only thing that comes to my mind is Image.makeFromEncoded(nsData.toByteArray()).toComposeImageBitmap() , but I would like to continue using SVGs for my icons.

Ok, as far as I can see also the official solution requires CocoaPods and the way to avoid this is not documented.

Does somebody figured out how to do it and can provide an example?

For Bitmaps you can just use the new (since 1.4.0)

org.jetbrains.compose.resources.painterResource

which you can get via

implementation(compose.components.resources)

and for SVG a modified version of

androidx.compose.ui.res.SVGPainter and
androidx.compose.ui.graphics.vector.DrawCache

from the desktop implementation. It is actually quite simple because both desktop and iOS are based on Skia. I just had to modify the loader so that it can read from a ByteArray instead of a Java stream. You can read the raw ByteArray as a resource via the resource package mentioned above.

Thanks. Yes, I play around with that right now. I try to figure out what CocoaPods actually does in the mix and if I this can be done by a Gradle task.

you can use moko-resources without cocoapods

[Stefan Oltmann]

This is already compatible with Compose for iOS?

[alex009]

yes https://kotlinlang.slack.com/archives/C0BJ0GTE2/p1681373973987759

Nice, I will check that out 🙂 🙏

I had issues loading SVGs using painterResource
