09/27/2025, 7:01 AMHi, try the stable version of Kotlin 2.2.20.
Also, look above this error if you have another compilation error.

09/27/2025, 2:19 PMOh, I have already seen this one, try to build for only one apple target, comment the others
François
09/27/2025, 2:20 PMIf I’m right, That’s something I can’t fix, it seems to be a Kotlin compiler issue not a plugin one.
François
09/27/2025, 2:21 PMThe workaround is to go back to xcode 16.4

doesn't seems to be plugin issue
issue is with kotlin compiler itself

François
09/27/2025, 2:23 PMI guess, you can create a new issue on the JB tracker

09/27/2025, 2:29 PMI don’t know if there are aware about this issue with cinterop and xocde 26.
I don’t have a reproducer for the issue
