Hello guys,

I have function in common that returns ByteArray but on the iOS world it is converted to KotlinByteArray and not to NSData. In the Kotlin world I have the following extensions to convert ByteArray to NSData and visceversa.

private fun ByteArray.toNSData(): NSData = memScoped {
    return NSData.create(
        bytes = toCValues().getPointer(this),
        length = size.toUInt()
    )
}

private fun NSData.toByteArray(): ByteArray = memScoped {
    val size = length.toInt()
    val nsData = ByteArray(size)
    memcpy(nsData.refTo(0), bytes, size.toUInt())
    return nsData
}

Does someone know how I can convert KotlinByteArray to NSData and visceversa in Swift? 🙂

Wait, why can’t you just call your Kotlin extension in Swift?

[Jonas Bark]

you could do that, but they shouldn't be marked private then of course

I did not think about that LOL 😅

Thanks @ribesg! 🤜🤛
