The Reachability class Apple provides (https://developer.apple.com/iphone/library/samplecode/Reachability/index.html) is very useful. So useful in fact that it's used by many *many* libraries on iOS. Since Objective-C doesn't have namespaces, this means you frequently run into conflicts between libraries.

The functionality is so basic, and so core, I don't understand why it isn't provided by the OS directly. A simple NSReachability class would be a wonderful wonderful thing. It would also prevent newbie developers from using code like:

NSString *reachable = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"http://google.com"] encoding:NSUTF8StringEncoding error:&error];
if ([reachable rangeOfString:@"I'm feeling lucky!"].location != NSNotFound) {
    // has internet connection
}
