I’m having issues using optics’ ksp plugin within a multiplatform project with iOS targets. I get conflicting declarations from the generated code. (error in thread). I noticed that the same code is generated and put in all build/generated/ksp/metadata/commonMain/kotlin and build/generated/ksp/ios*/ios*Main/kotlin. Hence I get errors for each generated declaration for each ios target. Is it expected to have generated code for each target and not just in the common directory? The code I have annotated with @optics resides within the shared folder.
I’ve also created a minimum reproduce project (link in thread).

Error:

or perhaps this is because I have configured ksp for iOS targets as well?

add("kspIosX64", "io.arrow-kt:arrow-optics-ksp-plugin:1.2.1")
add("kspIosArm64", "io.arrow-kt:arrow-optics-ksp-plugin:1.2.1")
add("kspIosSimulatorArm64", "io.arrow-kt:arrow-optics-ksp-plugin:1.2.1")

however if I don’t, I won’t be able to use optics for ios specific code

perhaps it’s a ksp limitation?

you might try to do it only for commonMain, but I'm not really an expert on KSP + KMP 😕
