Comparing NSDates without time component

Question

In a swift playground, I have been using

NSDate.date() 

But, this always appears with the time element appended. For my app I need to ignor

Answer 1

There are several useful methods in NSCalendar in iOS 8.0+:

startOfDayForDate, isDateInToday, isDateInYesterday, isDateInTomorrow

And even to compare days:

func isDate(date1: NSDate!, inSameDayAsDate date2: NSDate!) -> Bool

To ignore the time element you can use this:

var toDay = Calendar.current.startOfDay(for: Date())

But, if you have to support also iOS 7, you can always write an extension

extension NSCalendar {
    func myStartOfDayForDate(date: NSDate!) -> NSDate!
    {
        let systemVersion:NSString = UIDevice.currentDevice().systemVersion
        if systemVersion.floatValue >= 8.0 {
            return self.startOfDayForDate(date)
        } else {
            return self.dateFromComponents(self.components(.CalendarUnitYear | .CalendarUnitMonth | .CalendarUnitDay, fromDate: date))
        }
    }
}
