'Unresolved reference: readln - in InteliJ IDEA
this code in a new project throws "Unresolved reference: readln" error
fun main() {
val z = readln()
}
But on another project in Intelij IDEA works ok. Why so?
Solution 1:[1]
readln() was added in Kotlin 1.6. Make sure you are using Kotlin 1.6 or later.
Solution 2:[2]
The readln function is only available since version 1.6.0 of Kotlin, see it's documentation
Most likely the other project uses an older version of Kotlin, in which this function was not available yet.

thanks!
I had to go to Preferences -> Languages & Frameworks -> Kotlin - and change Update channel from "Stable" to Early Access Preview 1.6.x or 1.7.x
