Collections

Kotlin and Swift have very similar kinds of collections and can be mapped between each other.

Explanations

Kotlin	Swift
List	Array
MutableList	NSMutableArray
Array	KotlinArray
Set	Set
Map	Dictionary
MutableMap	NSMutableDictionary

In Kotlin:

fun getList(): List<Int> {
    return listOf(1,2,3)
}

fun getArray(): Array<Int> {
    return arrayOf(1,2,3)
}

fun getMap(): Map<String, Int> {
    return mapOf("a" to 1, "b" to 2)
}

fun getSet(): Set<Int> {
    return setOf(1,1,2)
}

fun set(collection: List<Int>){
    println(collection)
}

In Swift:

let a: Array<KotlinInt> = CollectionsKt.getList()
let a2: KotlinArray<KotlinInt> = CollectionsKt.getArray()
let d: Dictionary<String, KotlinInt> = CollectionsKt.getMap()
let s: Set<KotlinInt> = CollectionsKt.getSet()
CollectionsKt.set(collection: [1,2,3])
