return the same byte offset

No, that cannot work. You'd at least know the offset (in bits) for it to be any useful, which is not something offset(of:) can provide.

It seems to be mentioned in a separate thread that they indeed are not addressable.

@Michael_Ilseman

If you have a struct with two Bool fields in it, those might not be addressable as they could be packed into separate bits of the same byte. If you want an address, Swift has to materialize the address for you and perform a write-back when you're done. Improving how that is done is(/was) the role of accessors and safety is helped by exclusivity.
