Cannot build KotlinMP example about blue-falcon HOT 9 CLOSED

Sounds very familiar, i recall having a similar issue before and cant remember what i did the fix it. Let me have a think about it.

from blue-falcon.

What version of Gradle and also kotlin?

Looks like the coroutines library used is of 1.3.70 and needs to be changed to a 1.4 one.

e: Could not find "/Users/lneumann/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlinx/kotlinx-coroutines-core-iosarm64/1.3.8/ab1f410af27e33b328b0e7b3b75875953822e9eb/kotlinx-coroutines-core.klib" in [/Users/lneumann/Projekte/SteigtUm/blue-falcon/examples/KotlinMP/iosApp, /Users/lneumann/.konan/klib, /Users/lneumann/.konan/kotlin-native-prebuilt-macos-1.4.10/klib/common, /Users/lneumann/.konan/kotlin-native-prebuilt-macos-1.4.10/klib/platform/ios_arm64].

Ok, that helped. Now there's another error I can't get rid of. I also had this one in my own project, that's why I wanted to try out the example to see if I'm doing wrong:

> Task :app:compileKotlinIos FAILED
e: /Users/<some path>/blue-falcon/examples/KotlinMP/app/src/iosMain/kotlin/sample/scan.kt: (3, 1): @Throws must have non-empty class list

FAILURE: Build failed with an exception.

If I remove the @Throws annotation, Xcode builds the project and runs the app. It seems to work fine at first sight, but in the console XCode outputs: Unknown error happened.

Try kotlin.native.Throws instead?

from blue-falcon.

Nope. Either I put the @Throws annotation above the method and get @Throws must have non-empty class list or I leave it out and get Function doesn't have or inherit @Throws annotation and thus exception isn't propagated from Kotlin to Objective-C/Swift as NSError. It is considered unexpected and unhandled instead. Program will be terminated.

I figured it out now. I can't call scan() directly from Swift. Instead, I need to use your MainCompat approach like shown here. Maybe you could explicitly state that in the documentation? And I also see that @UseExperimental is deprecated and the NSBluetoothAlwaysUsageDescription is missing, so I think updating the example would also be a good idea.

from blue-falcon.

Ah, yes that was it.
Could you possibly do a PR with the changes?

Thanks

I found that by using the coroutine native-mt dependency we can completely get rid of MainCompat. Everything should be up to date now.
