Hi folks, please let me know if this is not the correct channel, I've a KMP application targeting Android and iOS. On iOS, I'm upgrading Kotlin from 1.9.20 to 2.0.20. I've run into a small issue, where some of the Objective-C method names have underscore at the end. The names are name, value, type, set and start. I couldn't find any documentation on this behaviour change in upgrade notes. Is there a list somewhere?

From searching, I've seen some discussion on Github and SO but no clear explanation or behavior.
1. Is there a list of keywords that get mangled?
2. Is this because of conflicts? I've checked the generated header file and apart from type, there shouldn't be a conflict with any other names with any other interfaces.

Underscores happen when there are naming conflicts. For example if you have two Kotlin things called name that can't have the same name in Objective-C, then one of them will become name_. That behavior has always existed, so I'm not sure what changed between 1.9.20 and 2.0.20 to cause you to see it happen in places it wasn't happening before.

are you using any 3rd party library? In my case I ran into a bunch of errors due to lack of support by Realm. Maybe check your if your libraries support kotlin 2.0+

No, I'm not using 3rd party libraries.

I guess I'll have to live with it. There's no conflicting method names that I found but it's an internal API, so I can refactor Objective-C side. 🙁
