How I can pass String to variable type URL?

[lukavucko]

Hi,
I got something like this:

interface Base {
var url: URL?
}

class BaseImpl: Base {
override var url: URL? = null
}

Now in my test I want to pass this:
url = "http://www.countries-list.info/Download-List/download.txt"
but of course I got this error:
^ Type mismatch: inferred type is String but URL? was expected

Does anyone knows how it should be solved?
I know that URL object accept string as parameter URL(String spec)
but I don't know how to implement that in my case.
Thank you in advance

Hello! First of all, I got to remind you about Kotlin/Native issue tracker migration(see #4079). Bugs should be reported to the YouTrack, also one can ask for the community help on the #kotlin-native slack channel. Some known questions are answered on the StackOverflow, ask the new one can be done here.
About this particular question. As far as I can see, you're trying to use java.net.URL class, correct? This class is not available for Kotlin/Native. The whole point of Kotlin/Native is to provide programming with Kotlin but without JVM used. Therefore, no Java packages will be available for it.
If it's not Kotlin/Native, you can probably do something like url = URL(spec = "http://www.countries-list.info/Download-List/download.txt").
