ios - Swift - Sorting By Date Issue -

i'm using nssortdescriptors sort array date element. date set string using formatter formats in style : "dd/mm/yy hh:mm". date element stored inside dictionaries stored in array. parts of code below:

// date formatting let currenttime = date() let timeformatter = dateformatter() timeformatter.locale = locale.current timeformatter.dateformat = "hh:mm dd/mm/yy" let convertedtime:string! = timeformatter.string(from: currenttime)  // descriptor let descriptord: nssortdescriptor = nssortdescriptor(key: "date", ascending: false)  // dictionary let newuserrecord = [     "name"  : enteredname!,     "score" : self.gamescore,     "date"   : convertedtime ] [string : any]  // sorting  newuserarray.sort(using: [descriptord]) 

however problem date being sorted time (hh:mm) , not taking in account (dd/mm/yy) part. example if sort date , have date of 13:12 19/11/16 , date of 09:12 18/11/16 09:12 date appear first though should 13:12 day later. how fix this?

this object oriented swift way:

declare struct rather dictionary , include time formatter

struct user {     let timeformatter : dateformatter = {       let formatter = dateformatter()       formatter.locale = locale.current       formatter.dateformat = "hh:mm dd/mm/yy"       return formatter    }()     let name : string    let score : int    let time : date     var convertedtime : string {       return timeformatter.string(from: time)    }  } 

declare array of user type , add 2 instances

var newuserarray = [user]()  newuserarray.append(user(name: "foo", score: 12, time: date().addingtimeinterval(1000.0))) newuserarray.append(user(name: "bar", score: 78, time: date())) 

sort array time descending

newuserarray.sort(by: {$0.time > $1.time }) 

and print formatted date

print(newuserarray[0].convertedtime)
