Hi, debugging the iOS platform on KMP is proving to be a bit complicated. I am not sure if I am doing something wrong, but is it not possible to inspect variables or evaluate expressions using the intelliJ debugger? I can set the breakpoints fine but when it comes to seeing the snapshot of my objects I don’t get any output, just errors.

Hey I am not able to use String.format in Shared module that is powered by KMM. Does anyone has any clue?

is there is a multiplatform library for URL Encoding with parameter?

Hey ! I want to ask people around if

runCatching

is in use in any of your Kotlin (or Android) projects ? I feel my team is abusing it and I'm trying to understand if there's any "pros" about using it in any coroutine-based codebase. My team just adopted this convention and I'm at loss of words. (Examples in thread for anyone interested)

hi there, I'm trying to run an UI test in shared/commonTest and facing the following NPE. This tests works fine when I run it in androidInstrumentedTest. Any ideas?

java.lang.NullPointerException: Cannot invoke "String.toLowerCase(java.util.Locale)" because "android.os.Build.FINGERPRINT" is null

Hi folks. I want to upload a huge multipart file to my server via Ktor Client. Any ideas or tips? The file is considered to be larger than 2GB.

Hello, Seeing

w: Kapt currently doesn't support language version 2.0+. Falling back to 1.9.

in logs means it applies only for kapt right? i.e rest of the project is using kotlin 2.0, but kapt itself is falling back kotlin 1.9? Context: we have upgraded most of our modules to use kotlin 2.0 & ksp, but only 2 modules are using

id("kotlin-kapt")

(because of room-java) I'm guessing we will still be able to use kotlin 2.0 in those modules using kotlin-kapt, right?

How do we configure serialization now with Ktor 2.0 on an Android client? This example for previous versions is deprecated and no longer works:

client = HttpClient(Android) {
    install(JsonFeature) {
      serializer = KotlinxSerializer()
    }
}

The migration guide says to use the content negotiation plugin, but there are no examples of how to do this on Android that I can see.

Hi, how can I convert a Swift

NSData

to Kotlin

ByteArray

? Background: I’m working on a Kmp library where we need to use OS’s crypto API to encrypt data. So, in Kmp library we define an Interface

interface MessagePackHelper {
    fun serialize(payload: String): ByteArray
}

from iOS, we need to implement this interface and set back to the Kmp library. So in Swift, we need to implement below method:

func serialize(payload: String) -> KotlinByteArray {
        // let encyrpted = encrypt(payload) // result is NSData obect
        // todo - would like to convert NSData -> KotlinByteArray
    }
