iOS linker error with 0.4.0 on macbook

[ardune]

I am getting an error (slightly different depending on xcode version) when attempting to run locally on iOS simulator:

Attached is a minimal repo solution which is a file -> new project for KMP and then adding "dev.whyoleg.cryptography *" for testing
CryptoTest.zip

Macbook (M3 / apple silicon) when attempting to use "openssl3-prebuilt"

I've attempted to use xcode 15.1, 15.3, 15.4, and 16.0

All of the above work when using
"dev.whyoleg.cryptography:cryptography-provider-apple:0.4.0"
but fail when using
"dev.whyoleg.cryptography:cryptography-provider-openssl3-prebuilt:0.4.0"

I am very new to KMP platform so please let me know if there extra information that would be helpful.

Hey!
Thanks for raising the issue and providing the reproducer! This looks very similar to #8. I will take a look in coming days on what is really happening.

A bit late but I decided to look into this a bit more and it turns out that kotlin 2.0.0 doesn't work, but kotlin 2.0.21+ does - I was able to test 2.1.0 and 2.0.21 successfully using the sample above.

Glad that the issue was resolved!
Probably this is because 0.4.0 is using kotlin 2.0.20.

I'm still planning to create some integration test for this case, to be sure that everything will work in future.
