[rhonyabdullah]

Hi @Alex009
Could you help me with pod integration, i try to follow moko-template project structure but ends up with this error, i'm not have idea why ‘inputDir’ not generated by the gradle task probably syncMultiPlatformLibraryDebugFrameworkIosX64
here my verbose log:

Sorry for delay. Sync task in inputDir use output sir of link task. Can you run not pod install, but just ./gradlew syncMultiPlatformLibraryDebugFrameworkIosX64 ? This task should run link task and use output of link

[rhonyabdullah]

No problem, here is :

./gradlew syncMultiPlatformLibraryDebugFrameworkIosX64
