Date parsing

[travis]

If anyone needs to work with NSDate, here's a snippet that specifies a format and reads dates from a plist. It also finds the seconds / interval between each date and the startDate.

override func setup() {
        let df = NSDateFormatter()
        df.dateFormat = "MMM d, y, hh:mm:ss a"//Apr 11, 2016, 10:00:00 AM

        if let path = NSBundle.mainBundle().pathForResource("date", ofType: "plist") {
            if let array = NSArray(contentsOfFile: path) as? [NSDate] {
                let startDate = array[0]
                let eventDate = array[1]
                let ti = eventDate.timeIntervalSinceDate(startDate)
                print(ti)
                print(ti/3600.0)
            }
        }
    }
}
