Cannot find type Kmp_observableviewmodel_coreViewModel in scope

Hi,

I just created an empty Kotlin Multiplatform project and tried to implement your framework on iOS side and this is what I get when I implement extension that you described in the tutorial:

Why is this happening and how can it be fixed? Thx

Hi, could you share the build.gradle.kts file of your shared Kotlin module?

  plugins {
      alias(libs.plugins.kotlinMultiplatform)
      alias(libs.plugins.androidLibrary)
  }

  kotlin {
      androidTarget {
          compilations.all {
              kotlinOptions {
                  jvmTarget = "1.8"
              }
          }
      }

      listOf(
          iosX64(),
          iosArm64(),
          iosSimulatorArm64()
      ).forEach {
          it.binaries.framework {
              baseName = "shared"
              isStatic = true
          }
      }

      sourceSets {
          commonMain.dependencies {
              //put your multiplatform dependencies here
          }
          commonTest.dependencies {
              implementation(libs.kotlin.test)
          }
      }
  }

  android {
      namespace = "com.example.myapplication"
      compileSdk = 34
      defaultConfig {
          minSdk = 34
      }
      compileOptions {
          sourceCompatibility = JavaVersion.VERSION_1_8
          targetCompatibility = JavaVersion.VERSION_1_8
      }
  }

It looks like you are missing the Kotlin implementation:

kotlin {
    sourceSets {
        all {
            languageSettings.optIn("kotlinx.cinterop.ExperimentalForeignApi")
        }
        commonMain {
            dependencies {
                api("com.rickclephas.kmp:kmp-observableviewmodel-core:1.0.0-BETA-2")
            }
        }
    }
}

I do that and still receive the same error in iOS

You'll only see the Kotlin declarations that are part of the public API of your shared module. So before the Kmp_observableviewmodel_coreViewModel type becomes visible in Swift, you would also need to create a ViewModel in Kotlin. Once you have a ViewModel both the ViewModel class and the Kmp_observableviewmodel_coreViewModel type should be visible from Swift.

Oh okay, thx. Can you pls include this in the tutorial just so iOS devs know. I lost entire day trying to figure out why my new project is not recognizing that extension
