Hello everyone,
I have a problem when importing cocoapods libraries on the latest Kotlin release 1.7.20. I have a project integrating KMM for mobile platforms. Until recently integrating cocoapods via native.cocoapods plugin used to link platform.CoreGraphics lib to the generated .knm file. Thus making functions like CGSize automatically linked to the platform lib instead of building its own classes. But lately I have upgraded to the latest Kotlin features and this behaviour seems to have disappear. Here is an example of what used to work for me and what I would like to return to if possible:
Here is the gradle definition:
build.gradle.kts
plugins {
kotlin("multiplatform")
kotlin("native.cocoapods")
kotlin("plugin.serialization")
id("com.android.library")
}
kotlin {
android()
iosX64()
iosArm64()
iosSimulatorArm64()
cocoapods {
version = "1.0.0"
summary = "..."
homepage = "..."
ios.deploymentTarget = "10.0"
podfile = project.file("../../../appleSystem/Podfile")
framework {
...
}
xcodeConfigurationToNativeBuildType["CUSTOM_DEBUG"] = org.jetbrains.kotlin.gradle.plugin.mpp.NativeBuildType.DEBUG
xcodeConfigurationToNativeBuildType["CUSTOM_RELEASE"] = org.jetbrains.kotlin.gradle.plugin.mpp.NativeBuildType.RELEASE
pod("UIColor-HTMLColors") { version = "~> 1.0.0" }
pod("PinLayout") { version = "~> 1.10.3" }
pod ("MarqueeLabel"){ version = "~> 4.3.0"}
pod ("BadgeSwift") { version = "~> 8.0"}
pod("Reachability") { version = "~> 3.2"}
}
sourceSets {
...
}
}
android {
...
}
This still synchronize and compile. Though, if you take BadgeSwift pod for instance (others have the same issue), the generated knm file will look something like this:
// IntelliJ API Decompiler stub source generated from a class file
// Implementation of methods is not available

As you can see in the method setInsets for exemple:
@kotlin.commonizer.ObjCCallable public open external expect fun setInsets(insets: kotlinx.cinterop.CValue<cocoapods.BadgeSwift.CGSize>): kotlin.Unit { /* compiled code */ }
The argument the pod is waiting for is a CGSize that is defined in cocoapods.BadgeSwift. Therefore the package has its own CGSize instead of using the one that is accessible in platform.CoreGraphics. The linkage used to be done automatically before resulting rather in something like that:
@kotlin.commonizer.ObjCCallable public open external expect fun setInsets(insets: kotlinx.cinterop.CValue<platform.CoreGraphics.CGSize>): kotlin.Unit { /* compiled code */ }
I though I could come back to the old behaviour by overriding the .def file generated for the pod:
tasks.named<org.jetbrains.kotlin.gradle.tasks.DefFileTask>("generateDefBadgeSwift").configure {
doLast {
outputFile.writeText("""
depends = platform.CoreGraphics
language = Objective-C
modules = BadgeSwift
""".trimIndent())
}
}
but this does not seem to work and I can’t find seem to find any subject related to that matter on the web. Could someone help me understand my problem here please. I am still pretty new to KMM, maybe I should use other def flags to import the CoreGraphics framework ? Am I expecting something that should not have been there in the first place ?
Thank you for your time,
Best regards
