However, it looks like you can use the simpler form:
hostArray addObject: (NSString*)url.host]; // apparently converts it back to “nullability unspecified"
Hm, that’s simpler, but it’s kind of dangerous since you could get the type wrong. For instance:
[portString appendString: (NSString*)url.port]; // ouch!
NSString* host = url.host;
if (host)
[hostArray addObject: host];
Yeah, that’s safe. I might still try to come up with an IF_LET() macro, though…
