Analyzing dependencies
[!] Failed to load 'shared' podspec: 
[!] Invalid `shared.podspec` file: 

        Kotlin framework 'shared' doesn't exist yet, so a proper Xcode project can't be generated.
        'pod install' should be executed after running ':generateDummyFramework' Gradle task:

            ./gradlew :sample:shared:generateDummyFramework

        Alternatively, proper pod installation is performed during Gradle sync in the IDE (if Podfile location is set).
