# multiplatform

When using the ios platform target for multiplatform, is it possible to get rid of this error when placing actual declarations in the Platform file?

Object ‘Platform’ has several compatible actual declarations in modules ab-testing-firebase.client.iosArm64Main, ab-testing-firebase.client.iosMain

how have you configured your source sets?

Here is my gradle.kts file:

Interesting when I changed my kotlin plugin to `

1.3.70

the workaround started to work. Now I need to wait till one of my dependencies gets republished with that kotlin version 🙂

Hi, @spierce7! Try to set this Gradle property in your project:

kotlin.mpp.enableGranularSourceSetsMetadata=true

The same problem as here. Also, are you using the same Gradle-IDEA-Kotlin versions as listed in this ticket?

[spierce7]

I’ll give that a shot. Thanks
