Hi there! I use kotlin.cocoapods plugin to import my shared code into my ios project (as described here https://github.com/JetBrains/kotlin-native/blob/master/COCOAPODS.md). My script_phases section in .podspec file:

spec.script_phases = [
    {
        :name => 'Build multiplatform',
        :execution_position => :before_compile,
        :shell_path => '/bin/sh',
        :script => <<-SCRIPT
            set -ev
            REPO_ROOT="$PODS_TARGET_SRCROOT"
            "$REPO_ROOT/../gradlew" -p "$REPO_ROOT" :multiplatform:syncFramework \
                -Pkotlin.native.cocoapods.target=$KOTLIN_TARGET \
                -Pkotlin.native.cocoapods.configuration=RELEASE \
                -Pkotlin.native.cocoapods.cflags="$OTHER_CFLAGS" \
                -Pkotlin.native.cocoapods.paths.headers="$HEADER_SEARCH_PATHS" \
                -Pkotlin.native.cocoapods.paths.frameworks="$FRAMEWORK_SEARCH_PATHS"
        SCRIPT
    }
]

When I build my ios project it runs syncFramework task and I don’t understand how syncFramework works.

Here are few examples:
1. I add some println("") inside a SharedCode function and when I build ios project the syncFramework does nothing. (I don’t see my println at runtime)
2. I change some function name fun test() -> fun myTest() then Xcode says test() func isn’t exist and if I change it to myTest() it compiles and crushes at runtime with unrecognized selector sent to instance
For now the only way to rebuild all the project it to delete the build folder from SharedCode and run Xcode build again.

Does it work as expected?

the syncFramework task basically make a copy of the produced framework on your KMP module build folder to the Pod local framework folder

[magnumrocha]

when you build your KMP library, an Apple framework is produced in the module's build folder...

[magnumrocha]

the syncFramework task is added as a build step in XCode for the Pod that represents your library....

[Rostislav Utrobin]

When I delete KMP build folder and run Xcode build the build folder (with Apple framework) will be created during the build. Who exactly will compile the framework?

[magnumrocha]

the syncFramework task depends on build task in gradle

[magnumrocha]

so, If the KMP is not built yet, the build will runs before the syncFramework

[Rostislav Utrobin]

Ok. What if KMP was built already. Does the build task understand that code was changed and it should recompile the framework ?

[magnumrocha]

well, is that what is expected, but I always build my KMP module by hand when I change any code on it

[magnumrocha]

and then I go to XCode...

[Rostislav Utrobin]

Got it. I want to reach the flow: I start build in Xcode. build task sees the code was changed and recompile it (or just uses existed code if wasn’t changed)

[magnumrocha]

flow = XCode build -> KMP Pod build -> syncFramework -> KMP Lib build in gradle (if not already build)

[Rostislav Utrobin]

Yeah. But I want the flow = Xcode build -> KMP Pod build -> syncFramework -> KMP Lib build in gradle (if not already built or my KMP code has any changes since last build)
