nsdate

How can I convert this string "2016-04-14T10:44:00+0000" into an NSDate and keep only the year, month, day, hour? The T in the middle of it really throws off what I am used to when working with dates. Convert the ISO8601 sting to date let isoDate = "2016-04-14T10:44:00+0000" let dateFormatter = DateFormatter() dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ" dateFormatter.locale = Locale(identifier: "en_US_POSIX") // set locale to reliable US_POSIX let date = dateFormatter.date(from:isoDate)! Get the date components for year, month, day and hour from the date let calendar = Calendar.current

I have two NSDate objects and I want the difference between the two and the result should again be a NSDate object. Any idea how to achieve this? Here, I am trying to address a unique problem where I have to find out the elapsed time and then localize the elapsed time. I can localize it if I have the elapsed time in NSDate object. So thought of creating a NSDate object which has its time component same as time interval between the two dates so that I could use NSDateFormatter to localize it.
