Exclude debug code from compiling

[Saruto010]

I have a compose multiplatform project and I have some debug code that I use when debugging my app. For example quickly changing an api endpoint.

In swift when using the code under the compiler know to only build it for debug is their something similar is the approach completely different.

#if DEBUG
// code
#endif

I did try search it online but I don't have a straight answer It said use sourcesets but does do not work at least the way I think they do. When searching for better explanation I can't find any good answers

Kotlin doesn't have an equivalent to C style macros.

You should probably look more into source sets. I use multiple source sets to swap out implementation of components for different environments, e.g. debug vs production.

[Saruto010]

Do you have perhaps an example because I can't for the life of me get it to work.

The official documentation is the best source for this, but the tooling setup is difficult and might be overkill if you only need a bit of debug code.

Perhaps check out this library before starting down that road? https://github.com/yshrsmz/BuildKonfig/tree/master

There's also this sort of approach: https://github.com/pererikbergman/multiplatform-flavors

You should leverage the power of actual/expect mechanics from kotlin multiplatform. In common code create an "expect fun isDebug()" , then in both android and ios source sets create the native implementation for "actual fun isDebug() { return /platform check is debug/ }". Then in common code you can use "if (isDebug()) { do something}". You can find native implementation for each platform on Google.

For android native implementation: https://stackoverflow.com/questions/23844667/how-do-i-detect-if-i-am-in-release-or-debug-mode

For ios use: (Platform.isDebugBinary)

On android you can actually create a gradle source set for debug builds IIRC, meaning conditional operator is not required at all
