Greetings,

I’m trying to add a CocoaPod dependency to my project. As a starting point, I used the examples in https://github.com/Kotlin/kmm-with-cocoapods-sample. However, I’m getting “Failed to generate cinterop” for all the dependent CocoaPods.

Is this a known issue with generating cinterop, or is there something broken with my Xcode config?

The actual error looks like:

> Task :kotlin-library:cinteropPod_dependencyIosArm64

Do you use latest Kotlin and Xcode versions?

Thanks.

Just figured that out myself. To answer my own question, the issue seems to be resolved by updating to 1.9.23 (I’m not ready to jump to 2.0).
