Trying to understand what Pasan did at 6:15?

I don't understand what Pasan did when he wrote.

return dateFormatter.stringFromDate(weatherDate)

and why did he change this line from Int to String

var currentTime: String

Hi Frank,

The stringFromDate method accepts a NSDate instance in which returns as a String using the format we specified just above our return statement, because we have access an a UNIX date we pass the value of it to our dateStringFromUnixtime method which gives us a human readable date string instead of numbers which don't make much sense.

Changing currentTime to be a String is required since as I said above stringFromDate returns a string therefore the type Int is a mismatch and would trigger a compiler error.

Hope that helps.
