How to compare 2 dictionaries in swift 3

Question

Hello I am getting duplicated Dictionaries from my service.

[{
DisplayName2 = "ABC";
Employee = "<null>";
EmployeeCode = 17227;
ImagePath = "/profile/image/759006c5e4214f0";
LeaveDetail = "<null>";
LeaveDetailLeaveDate = "2017-07-04T00:00:00";
LeaveEntry = "<null>";
LeaveEntryEndDate = "2017-07-04T00:00:00";
LeaveEntryNoOfDays = 1;
LeaveEntryStartDate = "2017-07-04T00:00:00";
LeaveEntryStartDateSession = FH;
LeaveType = "<null>";
LeaveTypeCode = 1;
LeaveTypeName = ANNUAL;
RequestStatus = C;
Shift = "<null>";
ShiftName = "";
SystemLeaveTypeCode = ANN;
TomorrowLeaveCount = 0;

},

{
DisplayName2 = "ABC";
Employee = "<null>";
EmployeeCode = 17227;
ImagePath = "/profile/image/759006c5e4214f0";
LeaveDetail = "<null>";
LeaveDetailLeaveDate = "2017-07-04T00:00:00";
LeaveEntry = "<null>";
LeaveEntryEndDate = "2017-07-04T00:00:00";
LeaveEntryNoOfDays = 1;
LeaveEntryStartDate = "2017-07-04T00:00:00";
LeaveEntryStartDateSession = FH;
LeaveType = "<null>";
LeaveTypeCode = 1;
LeaveTypeName = ANNUAL;
RequestStatus = C;
Shift = "<null>";
ShiftName = "";
SystemLeaveTypeCode = ANN;
TomorrowLeaveCount = 0;

},

{
DisplayName2 = "ABC";
Employee = "<null>";
EmployeeCode = 17227;
ImagePath = "/profile/image/759006c5e4214f0";
LeaveDetail = "<null>";
LeaveDetailLeaveDate = "2017-07-10T00:00:00";
LeaveEntry = "<null>";
LeaveEntryEndDate = "2017-07-10T00:00:00";
LeaveEntryNoOfDays = 1;
LeaveEntryStartDate = "2017-07-10T00:00:00";
LeaveEntryStartDateSession = FH;
LeaveType = "<null>";
LeaveTypeCode = 2;
LeaveTypeName = CASUAL;
RequestStatus = C;
Shift = "<null>";
ShiftName = "";
SystemLeaveTypeCode = CAS;
TomorrowLeaveCount = 0;

},

{
DisplayName2 = "ABC";
Employee = "<null>";
EmployeeCode = 17227;
ImagePath = "/profile/image/759006c5e4214f0";
LeaveDetail = "<null>";
LeaveDetailLeaveDate = "2017-07-10T00:00:00";
LeaveEntry = "<null>";
LeaveEntryEndDate = "2017-07-10T00:00:00";
LeaveEntryNoOfDays = 1;
LeaveEntryStartDate = "2017-07-10T00:00:00";
LeaveEntryStartDateSession = FH;
LeaveType = "<null>";
LeaveTypeCode = 2;
LeaveTypeName = CASUAL;
RequestStatus = C;
Shift = "<null>";
ShiftName = "";
SystemLeaveTypeCode = CAS;
TomorrowLeaveCount = 0;

}]

I want to compare these objects and only 1 object should be added into a new array. I can't use "==" to compare 2 dictionaries. How can I do this? Please help me Thanks

EDIT

if((obj==previouldObj)==false)
                            {
                                 self.arrayForTable.append(obj)
                            }

Then outside of the class public func ==(lhs: [AnyHashable: Any], rhs: [AnyHashable: Any] ) -> Bool { return NSDictionary(dictionary: lhs).isEqual(to: rhs) }

They are doing that for a purpose. So I need to handle it in my side — user1960169, Jul 05 '17 at 13:01

@Larme where I should put convenience init(dictionary otherDictionary: [AnyHashable : Any])? — user1960169, Jul 05 '17 at 13:57
You don't have to put `public convenience init(dictionary otherDictionary: [AnyHashable : Any])` anywhere in your code. He just pointed out that Swift's `Dictionary` can be casted to `NSDictionary`. Casting to `NSDictionary` is required because you have to use `isEqual(to:)` method of NSDictionary class. — nayem, Jul 05 '17 at 14:44
Consider changing `if((obj==previouldObj)==false){...}` to `if(!(obj==previouldObj)){...}` — nayem, Jul 05 '17 at 15:13
