NSString retain Count

by

The compiler is smarter than you.

It sees @"Hello world" and thinks “Aha! A constant string!”

It then sees [[NSString alloc] initWithString:@"Hello world!"] and thinks “Aha! An immutable object created with a constant string!”

It then collapses both of them down into a single NSConstantString, which has a retainCount of UINT_MAX, so that it can never be released.
