have anyone received this error trying to build a fat framework: Could not get unknown property 'FatFrameworkTask' for object of type org.jetbrains.kotlin.gradle.dsl.KotlinMultiplatformExtension?

[Kris Wong]

referencing https://kotlinlang.org/docs/reference/building-mpp-with-gradle.html

[Kris Wong]

gah! easy to miss that import statement at the top of the code sample 🤦

[tylerwilson]

Do you get this too when using it: it shows as unresolvable, but it does build. Disconcerting to see anything in red in the IDE (IntelliJ IDEA Community in my case).

[Kris Wong]

in my case idea highlights the hell out of build.gradle with warnings and errors

[Kris Wong]

i just had to get used to it

[tylerwilson]

in the case of using the FatFramework, what do you have for your sourcesets for iOS. the docs do not include this case, and I keep going round and round?

[Kris Wong]

iosMain {}
        iosX64Main {
            dependsOn iosMain
        }
        iosArm64Main {
            dependsOn iosMain
        }
        iosArm32Main {
            dependsOn iosMain
        }

[Kris Wong]

you can also specify that in the targets block using the sourceSets property

[tylerwilson]

cool, that is better. there ought to be a shorter version like listOf(iosX64Main,…) but this works. It is frustrating having to become a gradle groovy expert to get a build set up…

[Kris Wong]

welcome to the bleeding edge

[tylerwilson]

i feel bled out

[tylerwilson]

🙂

[Kris Wong]

the alternative is wait for stable

[tylerwilson]

So now I get this:

The following Kotlin source sets were configured but not added to any Kotlin compilation:
 * iosArm32Main
 * iosArm64Main
 * iosTest

[tylerwilson]

and the build fails.

[tylerwilson]

back to basics.

[tylerwilson]

btw, have you tried this one? https://github.com/AlecStrong/kotlin-native-cocoapods looks promising, but fails for me with some odd error.

[Kris Wong]

The source sets have to match your target names. Also, cocoapods integration is built in with 1.3.30.

[Kris Wong]

It's pretty nifty

[tylerwilson]

is that doc-ed anywhere?

[Kris Wong]

Yeah Google kotlin cocoapods and I'm sure it will pop up

[tylerwilson]

Got it. Thanks!

[tylerwilson]

Got the built-in cocoapods podspec working, but do you know how to set the basename of the generated framework/classes?

[tylerwilson]

Never mind. Found the answer is not supported. 😞

[Kris Wong]

binaries {
                    framework("$ios_framework_name")
                }

[Kris Wong]

it will end up creating 4 frameworks, but it will be named properly
