Swift 3 - Comparing Date objects

Question

I\'m updating my app to Swift 3.0 syntax (I know it\'s still in beta but I want to be prepared as soon as it released).

Until the previous Beta of Xcode (Beta 5) I wa

Answer 1

To compare date only with year - month - day and without time for me worked like this:

     let order = Calendar.current.compare(self.startDate, to: compareDate!, toGranularity: .day)  

                      switch order {
                        case .orderedAscending:
                            print("\(gpsDate) is after \(self.startDate)")
                        case .orderedDescending:
                            print("\(gpsDate) is before \(self.startDate)")
                        default:
                            print("\(gpsDate) is the same as \(self.startDate)")
                        }

Answer 2

from Swift 3 and above, Date is Comparable so we can directly compare dates like

let date1 = Date()
let date2 = Date().addingTimeInterval(50)

let isGreater = date1 > date2
print(isGreater)

let isSmaller = date1 < date2
print(isSmaller)

let isEqual = date1 == date2
print(isEqual)

Alternatively We can create extension on Date

extension Date {

  func isEqualTo(_ date: Date) -> Bool {
    return self == date
  }
  
  func isGreaterThan(_ date: Date) -> Bool {
     return self > date
  }
  
  func isSmallerThan(_ date: Date) -> Bool {
     return self < date
  }
}

Use: let isEqual = date1.isEqualTo(date2)
