it’s kind of dangerous since you could get the type wrong

It’s another example of the “any cast is a bug waiting to happen” problem that’s inherent in C-like languages.

For this situation it would be nice if there was a cast like this:

[hostArray addObject: (_Nonnull) url.host];

If it did a runtime check for not nil, that would be even better.
