Does anyone here have ` Serializable` working on multiplatfo

Question

Does anyone here have ` Serializable` working on multiplatform building for iOS Running into this build error ``` cannot access Serializable it is internal in <http kotlin io|kotlin io> ``` I ve checked the existing GH issues where it appeared people just had import plugin issues but I think I m doing that right `apply plugin kotlin multiplatform ` `apply plugin kotlinx serialization ` `implementation org jetbrains kotlinx kotlinx serialization runtime native $ versions serialization ` `import kotlinx serialization Serializable` Something I m missing

kgonyon · Answer

Are you trying to use ` Serializable` inside common or native source set I have it working for my multiplatform project which is building for ios

kgonyon · Answer

```apply plugin com android library apply plugin kotlin multiplatform apply plugin kotlinx serialization apply plugin maven publish ```

kgonyon · Answer

```iosMain dependencies implementation org jetbrains kotlinx kotlinx coroutines core native $kotlin coroutines version implementation org jetbrains kotlinx kotlinx serialization runtime native $kotlin serialization version ```

kgonyon · Answer

I had to make sure I was using gradle 4 7 as well

basher · Answer

trying to use it in common

basher · Answer

I m working without gradle metadata though due to SQLDelight and kotlinx libs using different gradle metadata versions

basher · Answer

< kgonyon> i m now trying this out in a new mpp sample project using gradle 4 7 and all that and i m doing the same thing as you but getting the same error What other dependencies do you have setup for your common code

kgonyon · Answer

``` commonMain dependencies implementation org jetbrains kotlin kotlin stdlib common $kotlin version implementation org jetbrains kotlinx kotlinx serialization runtime $kotlin serialization version implementation org jetbrains kotlinx kotlinx coroutines core $kotlin coroutines version implementation org jetbrains kotlin kotlin reflect $kotlin version ```

kgonyon · Answer

```kotlin native version=1 3 11 kotlin version=1 3 11 kotlin serialization version= 0 9 1 kotlin coroutines version=1 1 0```

basher · Answer

ah that was it i had org jetbrains kotlinx kotlinx serialization runtime common instead of org jetbrains kotlinx kotlinx serialization runtime thanks this gets me closer to figuring it out in my larger project

kgonyon · Answer

No problem Glad I could help some

Drew · Answer

< basher> I m also trying to figure out how to do this except w coroutines when Gradle metadata is disabled because I need SQLDelight If you remember can you let me know when you figure it out

basher · Answer

thumbsup if I figure it out i ll def update here slightly smiling face

basher · Answer

Figured it out For your iOS targets you need to add ``` impelementation org jetbrains kotlinx kotlinx serialization runtime native debug ios arm64 $ versions serialization ` impelementation org jetbrains kotlinx kotlinx serialization runtime native release ios arm64 $ versions serialization ` ```

basher · Answer

use those instead of just plain ` native`

basher · Answer

and then you do the same for sim but ` iosx64`

Drew · Answer

< basher> nice It seemed to be working until I changed some dependencies around or did a clean build or something and then started getting some weird error ``` exception java lang IllegalStateException Could not find Users gradle caches modules 2 files 2 1 org jetbrains kotlinx kotlinx serialization runtime native debug ios arm64 0 9 1 b0a5a1202ec09423abf641fd47393aade3172064 kotlinx serialization runtime native debug ios arm64 0 9 1 klib in Users Projects HelloKotlinMPP Users konan klib Users konan kotlin native macos 1 0 3 klib common Users konan kotlin native macos 1 0 3 klib platform ios x64 ```

Jonas Bark · Answer

`implementation org jetbrains kotlinx kotlinx serialization runtime native $serialization version ` works fine for me for iOS targets

Drew · Answer

< Jonas Bark> even without having enabled Gradle metadata

basher · Answer

< Drew> hm not sure about that sorry

Drew · Answer

Yeah no worries I ll figure it out MPP seems so tricky right now with all the dependency management

Ashley Figueira · Answer

< Drew> indeed

Drew · Answer

I really want to dive in and create some cool stuff but it ll only be useful beneficial in my org w stuff working decently on iOS and it seems like iOS native is just not there for dependency management and coroutines in my experience anyway Guess I can learn enough to contribute a fix back to the repos though
