Is there a way of specifying a variable to be weak or unowned when running on iOS?

[svyatoslav.scherbina]

WeakReference class is supposed to be used instead.
http://kotlinlang.org/api/latest/jvm/stdlib/kotlin.native.ref/-weak-reference/index.html

Can this be used on multiplatform?

[svyatoslav.scherbina]

Yes. You can declare

expect class WeakReference<T : Any>(referred: T) {
    fun clear()
    fun get(): T?
}

in common sources,

actual typealias WeakReference<T> = java.lang.ref.WeakReference<T>

in Android sources and

actual typealias WeakReference<T> = kotlin.native.ref.WeakReference<T>

in iOS sources

Interesting, thanks
