How to determine build type in kotlin-multiplatform project

I’m working on a multiplaform project, iOS and JVM (I’m not targeting Android directly). Depending on the build type (debug or release) I want to configure the logging level (i.e. to print only errors in release). Since there is no a BuildConfig class available, how can I know from commonMain the build type?

Not a direct answer to the question, but for android/ios one can define a property like this:

in commonMain:

expect val isDebug: Boolean

in androidMain:

import com.yourPackage.BuildConfig

actual val isDebug = BuildConfig.DEBUG

in iosMain:

import kotlin.native.Platform

actual val isDebug = Platform.isDebugBinary

Note: for Android BuildConfig, you may need to add this in your app's Build.Config

android {
    buildFeatures {
        buildConfig = true
    }
}

It is not possible right now for all possible targets. Build type is resolved only for android.

But you can create two versions of the module e.g. module and module-debug.

Then declare in module:

const val IS_DEBUG = false

in module-debug:

const val IS_DEBUG = true

Finally in the resulting application or module gradle configuration you can declare dependency on what you need. E.g.:

if (DEBUG_ENV)  // you need to set DEBUG_ENV from property or environment variable
    implementation(project(":module-debug"))
else
    implementation(project(":module"))

or for android:

debugImplementation(project(":module-debug"))
releaseImplementation(project(":module"))

This way you can change logic using IS_DEBUG constant for every target or can create even completely different implementations of something in debug and release modules.
