AS is yelling at me after Kotlin 1.3, i’m assuming due to the new contracts:

private fun foo(value: String?) {
        var myString: String = ""

        if (!value.isNullOrEmpty()) {
            myString = value
        }
    }

IDE complains that there’s a type mismatch between

myString

and

value

, but the compile builds no problem (and warns if i explicitly

!!

). Is there anyway around this?

Did you update the IDE plugin? I pasted this into IJ (don’t have AS handy) and there are no issues.

this exact issue works for me in AS 3.3 with the latest kotlin plugin

Weird, i’m getting the error on both

3.2.1

and

3.3.0-beta01

Is the compiler smart enough to deal with .isNullOrEmpty and know that it's no longer nullable? I know it would do this if you put != null, but not sure with the function.

@mattinger Yes, check out Contracts: https://kotlinlang.org/docs/reference/whatsnew13.html#contracts
