Swift get HTML from URL

I am trying to get and print the HTML from a URL. Here's how I do it (with Swift 2):

let testUrl = NSURL(string: "https://www.google.com")
var html = NSString()
do {
    html = try NSString(contentsOfURL: testUrl!, encoding: NSUTF8StringEncoding)
} catch{print(error)}
print(html)

And the following error is printed in console:

Error Domain=NSCocoaErrorDomain Code=261 "The file couldn’t be opened using text encoding Unicode (UTF-8)." UserInfo={NSURL=https://www.google.com, NSStringEncoding=4}

Any idea?

It seems that www.google.com sends the response using the ISO 8859-1 encoding, the corresponding NSString encoding is NSISOLatin1StringEncoding:

html = try NSString(contentsOfURL: testUrl!, encoding: NSISOLatin1StringEncoding)

You can also detect the HTTP response encoding automatically, see for example https://stackoverflow.com/a/32051684/1187415.
