Swift Array type connected to Foundation NSArray class, how?

Question

In the Swift Language Guide, we read the following:

The Swifts Array type is bound to the Foundations NSArray class.

How can I associate Swift Arraywith the Foundation class NSArraywhen the first is a value type and the second is a reference type? Does an interface connect to an interface in a language to use code in another language?

Answer 1

The meaning / reference difference here is a little red herring.

typedef struct _Array {
    void * payload;
} Array;

Array c;
c.payload = malloc( /* Whatever */ );
Array d = c;
