# multiplatform

[Laurence Muller]

👋 Hello, I'm currently running into an issue where I have a simple test KMM project (depending on coroutines, ktor, serialization and decompose/mvikotlin) where things are fine on the Android side but on the iOS side things seem a bit odd.

The build job (from the KMM plugin) for iOS seems to be successful for the shared module

> Task :shared:compileKotlinIos
> Task :shared:linkDebugFrameworkIos
> Task :shared:syncFramework

BUILD SUCCESSFUL in 35s
3 actionable tasks: 3 executed

But then as soon as it starts building the swift app (unmodified demo app):

CompileSwiftSources normal x86_64 com.apple.xcode.tools.swift.compiler (in target 'iosApp' from project 'iosApp')

It keeps throwing a bunch of

<module-includes>:1:9: note: in file included from <module-includes>:1:
#import "Headers/shared.h"
        ^

              ^

#import "Headers/shared.h"

and keeps repeating a few times complaining about the things in Headers/shared.h and finally ending with:

/Users/xxx/Prototype/TestBaseApp/iosApp/iosApp/ContentView.swift:2:8: error: could not build Objective-C module 'shared'
import shared
       ^

** BUILD FAILED **


The following build commands failed:
	CompileSwift normal x86_64 /Users/xxx/Prototype/TestBaseApp/iosApp/iosApp/iOSApp.swift
	CompileSwift normal x86_64 /Users/xxx/Prototype/TestBaseApp/iosApp/iosApp/ContentView.swift
	CompileSwiftSources normal x86_64 com.apple.xcode.tools.swift.compiler

Any thoughts on if it is some kotlin syntax the compiler doesnt like or how I can make the compiler be a bit more verbose to point out what it is struggling with?
(I'm using kotlinVersion 1.5.21 and coroutines 1.5.0-native-mt)

Ok well that was dumb. Found the issue:

data class AppProperties(
    val DEBUG: Boolean, // <-- That's the culprit. Rename it, and it compiles.
    val APPLICATION_ID: String,
    val BUILD_TYPE: String,
    val FLAVOR: String,
    val VERSION_CODE: Int,
    val VERSION_NAME: String,
    val GIT_HASH: String,
    val MY_API_BUILD_ID: String,
    val MY_API_CLIENT_ID: String,
    val MY_API_CLIENT_NAME: String,
    val PLATFORM: String,
    val OS: String,
    val OS_VERSION: String,
    val PHONE_BRAND: String,
    val PHONE_TYPE: String
)

I can't have a variable named DEBUG in my data class or it will just fail to build
