Swift 3.0

guard let url = URL(string: "http://www.example.com") else {
    return
}

do {
    let html = try String(contentsOf: url)
}
catch {
    //handle `error` here
}

Swift 2.3

guard let url = NSURL(string: "http://www.example.com") else {
    return
}

do {
    let html = try String(contentsOfURL: url)
}
catch {
    //handle `error` here
}

Objective-C

NSString *url = @"http://www.example.com";
NSURL *urlRequest = [NSURL URLWithString:url];
NSError *err = nil;

NSString *html = [NSString stringWithContentsOfURL:urlRequest encoding:NSUTF8StringEncoding error:&err];

if(err)
{
    //Handle 
}
