How to determine if an NSDate is today?

Question

How to check if an NSDate belongs to today?

I used to check it using first 10 characters from [aDate description]. [[aDate descriptio

The correct and safe solution without force-unwrapping, working on Swift 2.2 and before iOS 8:

func isToday() -> Bool {
    let calendar = NSCalendar.currentCalendar()
    if #available(iOS 8.0, *) {
        return calendar.isDateInToday(self)
    }

    let todayComponents = calendar.components([.Era, .Year, .Month, .Day], fromDate:NSDate())
    let dayComponents = calendar.components([.Era, .Year, .Month, .Day], fromDate:self)

    guard let today = calendar.dateFromComponents(todayComponents),
        day = calendar.dateFromComponents(dayComponents) else {
        return false
    }

    return today.compare(day) == .OrderedSame
}
