I just have done so.

I found ConstUnsafePointer as a working replacement for CConstPointer.
No idea though whether this is correct or not. At least it compiles now.

I did iBooks → Store → Check for Available Downloads... and got told that all was fine.
No option to update my two Swift books.
Well, that is another problem for another day I guess.
