Boxing usually refers to out-of-line allocation of values on the heap. For
example, values of protocol type (as well as Any) will box their payload,
depending on size.

Thanks Slava,
Then my memory wasn’t that bad. This is indeed what I was thinking of, but I
should not have referred to it as ‘boxing’ ?

For what it’s worth, if T is a reference type or Unsafe*Pointer, then T and
Optional have the same exact representation in memory.
The compiler is smart enough to know that a non-optional pointer can never be
NULL, so a NULL value of the underlying type can be used to unambiguously
encode the ‘
I stand corrected.
I do/did think that there is a difference in the way it handles pointers
optionals and other optionals, but I now realise that even that could not be
the case.
So please ignore the last line in my previous post.

It means that a call to that function with an optional will unwrap the optional
before it is used.
That is quite neat when dealing with C-API’s because often you will receive a
pointer from a C-function which is optional to account for the fact that it can
be NULL (= nil).
By using a forced unw
It is an "implicitly unwrapped optional", or IOU.

Hello all,
I was wondering what an exclamation mark in a swift parameter listing
means. For instance, I used Elements Oxidizer Live to translate some
C# code into Swift. Reviewing it, I found the following (among
others):
@DllImport("ScriptHookV.dll")
private static __extern func scriptRegister(_ m
