将 Snowplow 添加到适用于 iOS 的 Kotlin 多平台项目

Question

I am trying to integrate Snowplow to a Kotlin Multiplatform Project.

Android is working fine:

val androidMain by getting {
        dependencies {
            api("com.snowplowanalytics:snowplow-android-tracker:1.7.1")
        }
    }

But integrating the iOS Cocoapod causes some troubles. I added the cocoapod plugin:

plugins {
    kotlin("multiplatform") version "1.4.32"
}

And the Snowlow pod:

kotlin {
    iosX64()
    iosArm64()
    cocoapods {
        pod("SnowplowTracker") {
            version = "~> 2.1.1"
        }
    }
}

Gradle sync results in the following error:

Exception in thread "main" java.lang.Error: /var/folders/gv/rc4dmzjs3wj9kt4kr00nwhdw0000gn/T/2185483547857483783.m:1:9: fatal error: module 'SnowplowTracker' not found

As I am Android developer I have basically zero knowledge about pods and their errors. I appreciate any hint towards a solution, as Google didn't help so far.

Answer 1

I would say the important thing here is to meet all requirements listed in the documentation . I'm mostly concerned if your project configures

summary , homepage , and frameworkName of the Podspec file in the cocoapods block.
version is a version of the Gradle project.

As I can see from the question, there is only pod() right now. Also, as the documentation and @Webfreak suggest, adding deploymentTarget might also help here.

Answer 2

I believe you also need to specify path to the podfile and (not sure if required) deployment target like this:

 cocoapods {
    ....
    podfile = project.file("../iosApp/Podfile")
    ios.deploymentTarget = "10.0"
 }

Also try to manually run cocoapod gradle tasks podImport and podInstall
