filter array of object by taking two object with same date

Question

I am trying to filter an array of objects on some conditions as:

filtered_shifts = myShifts.filter{$0.regionName == region && $0.cityName == city && $0.idNationality == idn && $0.quantityStaff != 0 && $0.shiftDate > todaydate}

I want to filter it more so if there is a shiftType == "night" and shiftType == "day" for the same shiftDate then added to my filtered shifts array.

if there is shift type = day AND type = night for same date then add it to my filtered array

how can i achieve this?

FOR EXAMPLE

Lets say that

   myShifts = {
       "id": 50,
        "id_region": 1,
        "id_city": 2,
        "id_nationality": 3,
        "id_service": 1,
        "shift_date": "2018-06-06 00:00:00",
        "shift_type": "day",
        "weekday": "wed",
        "quantity_staff": 5,
        "lead_hours": 3,
        "created_at": "2018-05-13 16:27:21",
        "updated_at": "2018-05-13 16:27:21",
        "deleted_at": null,
        "city_name": "Khobar",
        "region_name": "Eastren"
    },
    {
        "id": 70,
        "id_region": 1,
        "id_city": 1,
        "id_nationality": 3,
        "id_service": 1,
        "shift_date": "2018-06-06 00:00:00",
        "shift_type": "day",
        "weekday": "wed",
        "quantity_staff": 12,
        "lead_hours": 3,
        "created_at": "2018-05-21 14:03:02",
        "updated_at": "2018-05-21 14:03:02",
        "deleted_at": null,
        "city_name": "Dammam",
        "region_name": "Eastren"
    },
    {
        "id": 74,
        "id_region": 1,
        "id_city": 1,
        "id_nationality": 3,
        "id_service": 1,
        "shift_date": "2018-06-06 00:00:00",
        "shift_type": "night",
        "weekday": "wed",
        "quantity_staff": 20,
        "lead_hours": 3,
        "created_at": "2018-05-21 14:40:56",
        "updated_at": "2018-05-21 14:40:56",
        "deleted_at": null,
        "city_name": "Dammam",
        "region_name": "Eastren"
    },
    {
        "id": 4,
        "id_region": 1,
        "id_city": 1,
        "id_nationality": 4,
        "id_service": 1,
        "shift_date": "2018-05-15 00:00:00",
        "shift_type": "night",
        "weekday": "tue",
        "quantity_staff": 5,
        "lead_hours": 2,
        "created_at": "2018-04-23 11:46:20",
        "updated_at": "2018-05-15 10:33:29",
        "deleted_at": null,
        "city_name": "Dammam",
        "region_name": "Eastren"
    }

I want:

 filtered_Shifts =  {
        "id": 70,
        "id_region": 1,
        "id_city": 1,
        "id_nationality": 3,
        "id_service": 1,
        "shift_date": "2018-06-06 00:00:00",
        "shift_type": "day",
        "weekday": "wed",
        "quantity_staff": 12,
        "lead_hours": 3,
        "created_at": "2018-05-21 14:03:02",
        "updated_at": "2018-05-21 14:03:02",
        "deleted_at": null,
        "city_name": "Dammam",
        "region_name": "Eastren"
    },
    {
        "id": 74,
        "id_region": 1,
        "id_city": 1,
        "id_nationality": 3,
        "id_service": 1,
        "shift_date": "2018-06-06 00:00:00",
        "shift_type": "night",
        "weekday": "wed",
        "quantity_staff": 20,
        "lead_hours": 3,
        "created_at": "2018-05-21 14:40:56",
        "updated_at": "2018-05-21 14:40:56",
        "deleted_at": null,
        "city_name": "Dammam",
        "region_name": "Eastren"
    },

cuz in date 2018-06-06 there is shift_type = night AND day ...

Is there any possible value of shift_type other than night and day? — nayem

you can first check for night and day condition if true then use you above condition. — Abu Ul Hassan
