1.0.0-RC2 on iOS: Deserializer for declaration public kotlinx.serialization.json/Json|null[0] is not found #1110

I'm having the same issue. Did you find a solution? |
|
No. We've rolled back to 1.0.0-RC waiting for a fix |

Got the same error with 1.0.0-RC2. For Android works just fine |

I ran into the same issue. I was able to easily repro via the iosTest task, which made it easier to try different things to get it working. Changing coroutines to 1.3.9-native-mt or 1.3.9-native-mt-2 did nothing to change it. But I happen to also use Ktor in my shared library, and when I bumped that to the latest 1.4.1 version, the error above goes away and I can build and run successfully. So I suspect that Ktor 1.4.1 us pulling in some other newer dependency that makes things work, though I am unsure how to prove this. But if you are using Ktor, this may be a simpler fix. If not, perhaps simply including the dependency for it will make things work for you. |

Can someone provide a small project with reproducer? From what @tylerwilson said, I suspect that this caused by different transitive dependencies versions — if you have ktor that uses 1.0.0-RC, and trying to use RC2 in your project manually, this error happens. @SalomonBrys Ktor 1.4.1 uses serialization RC2. Can you upgrade your Ktor versions and check if the problem is resolved? |

Updating ktor to version 1.4.1 fixed the issue. |

After updating project to kotlin 1.4.10 I was still using dependency "kotlinx-serialization-core". With ktor 1.4.1 this gives next error for native framework build: It's because ktor 1.4.1 transparently adds "kotlinx-serialization-json:1.0.0-RC2" dependency, but ktor 1.4.0 does not, which gives me compilation error even for android build. After explicitly adding/replacing serialization dependency with "kotlinx-serialization-json:1.0.0" all works fine. I think error messages should be more clear, and many of transitive dependecies makes dependency hell. |

In case it helps anyone, this did the trick for me: https://youtrack.jetbrains.com/issue/KT-41378#focus=Comments-27-4457544.0-0. I was having a similar issue but with coroutines, so while it is not directly related it can still help. Basically you need to force the kotlinx-coroutines-core version to 1.3.9-native-mt-2 using this Gradle syntax: |
This has worked for me. Thanks a lot! and with the following versions for ktor, coroutines and serialization versions: ... |
We have an app that compiles fine for iOS using Kotlin 1.4.10 with Serialization core
1.0.0-RC.When I update Serialization core to
1.0.0-RC2and add the json dependency, it compiles & run fine on the JVM, but fails on Kotlin/Native for iOS with the following compilation exception:The text was updated successfully, but these errors were encountered:
