Sort array of custom objects by date swift

NSDate can't be compared with < directly. You can use NSDate's compare method, like in the following code:

meetingsData.sort({ $0.meetingDate.compare($1.meetingDate) == .OrderedAscending })

In the above code you can change the order of the sort using the NSComparisonResult enum, that in Swift is implemented like the following:

enum NSComparisonResult : Int {
   case OrderedAscending
   case OrderedSame
   case OrderedDescending
}

I hope this help you.

For Swift 3

meetingsData.sort(by: { $0.meetingDate.compare($1.meetingDate) == .orderedAscending})

OR

As dates are now directly comparable in Swift 3, For example.

   let firstDate = Date()
   let secondDate = Date()

   if firstDate < secondDate {    
   } else if firstDate == secondDate {        
   } else if firstDate > secondDate {        
   }
