What would be the easiest (and fastest) way to convert a pointer to an (unsigned)integer?
Ptr -> String -> Int
seems a bit cumbersome to me :-)

// Int to pointer:
let ptr = UnsafePointer<Double>(bitPattern: 123)!
print(ptr) // 0x000000000000007b
// Pointer to Int:
let int = Int(bitPattern: ptr)
print(int) // 123
Int has the same size as a pointer on both 32-bit and 64-bit platforms.

Excellent!
I had not seen the bitPattern initializer before…
