swift - Array not getting sorted -


i have array of structs. in struct have 2 nsdate objects: textlabel , detailtextlabel. i'm trying sort textlabel newest oldest date/time. , want detailtextlabel ordered based on textlabel. , want vice versa. here's code:

struct item {     let textlabel : nsdate     let detailtextlabel : nsdate }  var myitem = [item]()  myitem.insert(item(textlabel: mydatesecond, detailtextlabel: anotherdatesecond), atindex: 0) myitem.insert(item(textlabel: mydatethird, detailtextlabel: anotherdatethird), atindex: 0) myitem.insert(item(textlabel: mydatefirst, detailtextlabel: anotherdatefirst), atindex: 0)  @ibaction func sortbuttonsaction(sender: uibutton)  {     if sender == firstbtn {         myitem.sort({$0.textlabel.compare($1.detailtextlabel) == nscomparisonresult.orderedascending})     } else if sender == secondbtn {         myitem.sort({$0.detailtextlabel.compare($1.textlabel) == nscomparisonresult.orderedascending})     }     self.tableview.reloaddata() }

here's happens:

when select firstbtn, gets sorted way i'm expecting to. when press secondbtn, nothing happens.

what want happen

when secondbtn gets selected, want array sorted based on detailtextlabel data. why isn't happening?

to sort textlabel date: 

myitem.sort{$0.textlabel.compare($1.textlabel) == nscomparisonresult.orderedascending}

to sort detailtextlabel date:

myitem.sort{$0.detailtextlabel.compare($1.detailtextlabel) == nscomparisonresult.orderedascending}

you should choose better names vars. date, not label.
