Hello everyone. I really need your help, please save me :)

I added a new method in appleMain/Adversiment class

public val identifierString: String
    get() = identifier.toString()

The following code works fine in debug build , but it crash in release build 😞 I dunno more what to do .

withTimeoutOrNull(3000) {
    Scanner().advertisements.filter { it.identifierString == address}.collect{ adv ->
        Log.debug { "scanner - $adv" }
    }
    Log.debug { "scanner - completed" }
}

The exception is Uncaught Kotlin exception: kotlin.RuntimeException: Unexpected receiver type: kotlin.String

[travis]

Do you have the fullstack trace available to share?
Or, do you know which line specifically it is throwing the exception from?

In Debug build works fine

[Francis Mariano]

@travis I solved the issue (I guess).
I replace

public val identifierString: String
    get() = identifier.toString()

for that

public val identifierString: String
    get() = identifier.UUIDString()

I didn't understand the reason.

[travis]

Sorry that I was super busy at work and not able to help you sooner.

It is surprising that it would only fail on debug.
The Identifier type is different for the Apple platform, apparently that type doesn't properly adhere to toString.

Glad you found the solution and shared it.

[Francis Mariano]

Don't worry. Yeah, so stranger only fail on debug. I just uploaded a new version for the beta testers. Tks a lot
