swift - Changing one element in array changes all elements in the array -

i new swift , i'm trying mess around uitableviews , arrays.

i have array of type [day], named daysarray. i'm initiating array in viewdidload(), daysarray has 7 "days" in it.

also, have uitableview, being populated daysarray. when i'm trying change 1 day (one element in array), whole daysarray days changed , consequently, cells in uitableview same.
peculiar, don't know wrong (:

the day class:

import foundation  class day {      private var _name: string!     private var _starts: double!     private var _ends: double!      var name: string! {         {             if _name == nil {                 _name = "sunday"             }             return _name         }         set {             _name = newvalue         }     }      var starts: double! {         {             if _starts == nil {                 _starts = 8.00             }             return _starts         }         set {             _starts = newvalue         }     }     var ends: double! {         {             if _ends == nil {                 _ends = 20.00             }             return _ends         }         set {             _ends = newvalue         }     }      init(daydict: dictionary<string, anyobject>) {         if let dictname = daydict["name"] as! string! {             self._name = dictname         }         if let dictisworking = daydict["isworking"] as! bool! {             self._isworking = dictisworking         }         if let dictstarts = daydict["starts"] as! double! {             self._starts = dictstarts         }         if let dictends = daydict["ends"] as! double! {             self._ends = dictends         }     } } 

the code seems problematic is:

import uikit   let generaldaydict: [string : anyobject] = ["name" : "sunday" anyobject, "starts": 8.00 anyobject, "ends" : 20.00 anyobject] let someday: day = day(daydict: generaldaydict)    class viewcontroller: uiviewcontroller {      var daysarray: [day]! = []      override func viewdidload() {         super.viewdidload()          in 0...6 {             let generalday: day = someday             daysarray.append(generalday)          }         changearray()          // additional setup after loading view, typically nib.     }      func changearray() {         daysarray[5].starts = 6.00         day in daysarray {             print("each day in array starts at: ", day.starts)         }       } } 

the print command in changearray prints this:

each day in array starts at:  6.0 each day in array starts at:  6.0 each day in array starts at:  6.0 each day in array starts at:  6.0 each day in array starts at:  6.0 each day in array starts at:  6.0 each day in array starts at:  6.0 

as said, very peculiar... thank reading question, , answering of course (:

in loop instantiate objects same reference. have replace :

let generalday: day = someday 

by :

let generalday = day(daydict: generaldaydict) 

then able change attributes of generalday individually
