String With Contents Of Url Swift?

So before I downloaded the recent update, the following code worked for me:

var g_home_url = String.stringWithContentsOfURL(NSURL(string: url_string), encoding: NSUTF8StringEncoding, error: nil) // Gives me an error: "String.Type does not have a member names stringWithContentsOfUrl"

I am confused. What is the proper way to acieve the following objective-c method in swift?

NSString * g_home_url = [[NSString alloc] initWithContentsOfURL:[NSURL URLWithString:home_url] encoding:NSUTF8StringEncoding error:nil];

Answer Source

Use the -initWithContentsOfURL:encoding:error: instance method instead of the +stringWithContentsOfURL:encoding:error: class convenience initializer.

var g_home_url = String(contentsOfURL: NSURL(string: url_string)!, encoding: NSUTF8StringEncoding, error: nil)

I have no idea if class convenience initializers are now unsupported in Swift, but it would make sense as they were just shorthands for the alloc-init boilerplate, which doesn't exist in Swift.
