Hi
I'm having an issue to build a library shared between Android and iOS. The Android versions work fine, but when I try to create the artifact for Xcode I have the following error:

Hi @maxcruz, thanks for the report.
Could you reproduce the problem with 1.1.2 and provide dependencies section from build.gradle?

[maxcruz]

Hi @e5l thanks to you for your help.

Dependencies for the version 1.1.2 aren't in my repository. Which should I use?

Here are my Gradle files:

gradle.properties

# kotlin libraries
kotlin_version=1.3.20
coroutines_version=1.1.0

Update: To update to Ktor 1.1.2 it's necessary also upgrade Gradle to 4.10.X (4.10.3 in my case)
Apparently, related the problem is fixed with this update, but now I have a new one with the serializer.

Can't locate polymorphic serializer definition

Let try to investigate to fix that another issue to confirm if the update resolves the previous problem. Thanks

[maxcruz]

I can confirm that this problem is solved using Ktor 1.1.2, Kotlin 1.3.20 and Gradle 4.10.3
To fix the serializer issue I removed the @Serializable annotation from classes in the common module and provided the KSerializer interface separated.
Everything is working as is expected now. Thanks for your help.

I have the same issue on the latest release of Kotlin. Could you help with problem?

w: The compiler versions don't match either. Expected '[1.2]', found '1.1.2-release-6625'

# kotlin
kotlin_version=1.3.30
kotlin.incremental.multiplatform = true

# kotlin libraries
coroutines_version=1.1.1
ktor_version=1.1.2
serialization_version=0.10.0

# android
gradle_android_version=3.3.2

[e5l]

The ktor-client-ios 1.1.2 is not compatible with 1.3.30.

[sdetilly]

i have ktor-client-ios 1.1.3 and i also have this error message when i try upgrading kotlin to 1.3.30. Is there a ktor version that supports kotlin 1.3.30?

[sdetilly]

I was able to make it work by updating ktor lib to 1.1.4
