Realm (-SNAPSHOT) is incompatible with Kotlin 1.7.20-Beta

Hi all! I’m currently using Kotlin 1.7.20-Beta (which has the new memory management model enabled by default) with Realm 1.2.0-ktor2-SNAPSHOT on a multiplatform project.

At compile time, I’ve got the following error on all the classes that are using RealmObject. All works fine downgrading to Kotlin 1.7.10, with Realm 1.2.0-ktor2-SNAPSHOT and the new memory management model enabled in gradle.proprieties.

Let me know if you need additional tests/details.

Someone who comes across this make sure you are using -> kotlin(“multiplatform”).version(“1.7.20”), in my case it didn’t work with 1.7.20 & Realm 1.4.0

@paolorotolo, yes, it has been merged to the ktor2 branch as well and a SNAPSHOT has been released.
