@buenaflor I face the same errors as CI did https://github.com/getsentry/sentry-kotlin-multiplatform/actions/runs/4667538687/jobs/8263458621?pr=71
do make compile

[marandaneto]

@buenaflor So at the end of the day this didn't work at all for iOS, I tried myself but could not figure it out quickly.
Would you mind taking a stab and making it green on CI? I probably face the same errors as CI.

[buenaflor]

Yeah I'll take a look at it
