d15194 | From the error message one can see that your URL is a file URL:
file:///http:/i.imgur.com/rfw7jrU.gif
and error -1100 is kCFURLErrorFileDoesNotExist (see CFNetwork Error Codes Reference).
You should replace
NSURL(fileURLWithPath: urlString)
by
NSURL(string: urlString)

d15195 | Is there a difference with doing it this way?

d15196 | The int range issue is because you have an int literal. Use a double literal by postfixing 'd':
public static void main(String[] args) {
assignDoubleToInt(2147483646); // One less than the maximum value an int can hold

listing.type,

d15199 | Let's assume that each cluster can be described with the following attributes:
