And a build time error when i try to run the iosApp on Xcode:

"cannot find 'Greeting 'in scope"

and also this error

Failed to register bundle identifier (The app identifier "orgIdentifier.iosApp" cannot be registered to your development team because it is not available. Change your bundle identifier to a unique string to try again.)

please help out, thanks

Failed to register bundle identifier (The app identifier “orgIdentifier.iosApp” cannot be registered to your development team because it is not available. Change your bundle identifier to a unique string to try again.)

This doesn’t matter for now since you’re only building for a simulator. Bundle identifiers, provisioning profiles, etc. are needed when building to a device or distributing the app.

“cannot find ’Greeting ‘in scope”

This is probably because your kotlin module wasn’t built properly, therefore Greeting is unknown to the swift layer.

A problem occurred configuring project ‘:shared’.

> The project must have a target for at least one of the following platforms: ios_simulator_arm64.

That’s your problem. Could you reply with your build.gradle.kts ? Otherwise we won’t find out where your problem is.

This is the "build.gradle.kts(:shared)"

i saw a similar issue on stackoverflow: https://stackoverflow.com/a/70412493/13307007 but the answer doesn't fix it

[Solomon Tolu Samuel]

What i found to be the solution was to uncomment the "iosSimulatorArm64()" in the "build.gradle.kts(:shared)" but i dont know how ideal it is because whenever i run the iosApp on android studio it keeps on closing but it runs fine on Xcode

kotlin {
android()
iosX64()
iosArm64()
iosSimulatorArm64() //sure all ios dependencies support this target

cocoapods {
    summary = "Some description for the Shared Module"
    homepage = "Link to the Shared Module homepage"
    ios.deploymentTarget = "14.1"
    podfile = project.file("../iosLink/Podfile")
    framework {
        baseName = "shared"
    }
}

sourceSets {
    val commonMain by getting
    val commonTest by getting {
        dependencies {
            implementation(kotlin("test-common"))
            implementation(kotlin("test-annotations-common"))
        }
    }
    val androidMain by getting
    val androidTest by getting {
        dependencies {
            implementation(kotlin("test-junit"))
            implementation("junit:junit:4.13.2")
        }
    }
    val iosX64Main by getting

    val iosSimulatorArm64Main by getting
    val iosMain by creating {
        dependsOn(commonMain)
        iosX64Main.dependsOn(this)
        iosArm64Main.dependsOn(this)
        iosSimulatorArm64Main.dependsOn(this)
    }
    val iosX64Test by getting
    val iosArm64Test by getting
    //val iosSimulatorArm64Test by getting
    val iosTest by creating {
        dependsOn(commonTest)
        iosX64Test.dependsOn(this)
        iosArm64Test.dependsOn(this)
