What does this function RUNTIME_NOTHROW void Kotlin_initRuntimeIfNeeded() do? This function is in kotlin/kotlin-native/runtime/src/main/cpp/Runtime.cpp .
1. I found it got called all the time when trying to run my iOSApp, then I got a runtime exception when it ran into InitOrDeinitGlobalVariables(INIT_GLOBALS, result->memoryState); . It looks like the runtime environment had not fully created at that point, and it has already called OC bridge function, then caused an exception.
2. I also found another problem when using k/n. Top-level properties declared in kotlin will always return null when running iOSApp. I made it a top-level function and it worked. This problem also happened when KN was running into Kotlin_initRuntimeIfNeeded() .
3. btw, debug shared.framework and k/n lib with disasm showed in lldb is tough. Is there any way to debug k/n from source when running iOSApp?
Does anyone has any idea here?

Is this with the new memory model or old?

kotlin version is 1.5.31

[Joakim Forslund]

So what initRuntimeIfNeeded does is just to actually start/init the called library on the current thread if it already is not.

So it is a way to make sure you can access certain runtimes when doing threaded work

If you want to debug with xcode and not intellij https://github.com/touchlab/xcode-kotlin has some integration for that

Thx, is there any way to track code into jetbrain’s K/N source code when debugging iOSApp?

[Joakim Forslund]

you can look into https://plugins.jetbrains.com/plugin/14936-kotlin-multiplatform-mobile

which allows debugging

I think 2. could be fixed if you use 1.6.0 or higher, top level properties initialization logic was changed. 1. might be a bug, but I'd also try with latest Kotlin version before filing an issue.

Well, 2 was first found when using Kotlin 1.6.0 :-), I also tried 1.6.20-dev5891 and 1.5.31, it also happened
