Handle value types as if they were references or references as if they were value types in Swift

Abstract - ReferenceValueTypeWrappers.md

Reference / Value Type

The Reference wrapper class for any Type in Swift makes it possible to handle objects from structs, as if they were classes (e.g. imitates behavior of Java references.)

The ValueType wrapper on the other hand mimics the behavior of structs for class objects.

You can also wrap the same type into its wrapper, but this doesn't make sense, even though it is possible.

Reference.swift

class Reference<T> {
    var value: T
    init(_ value: T) {
        self.value = value
    }
}

ValueType.swift

struct ValueType<T> {
    var value: T
    init(_ value: T) {
        self.value = value
    }
}
