Data = (
{
"Dry_cleaning" = 49;
Iron = 8;
Name = "Shirt/Tees";
Wash = 15;
"Wash_Iron" = 19;
id = 1;
},
{
"Dry_cleaning" = 49;
Iron = 5;
Name = "Kurta(short)";
Wash = 20;
"Wash_Iron" = 19;
id = 2;
},
{
"Dry_cleaning" = 50;
Iron = 8;
Name = "Kurta(Long)";
Wash = 15;
"Wash_Iron" = 20;
id = 3;
},
{
"Dry_cleaning" = 50;
Iron = 5;
Name = Shorts;
Wash = 15;
"Wash_Iron" = 19;
id = 4;
},
{
"Dry_cleaning" = 55;
Iron = 8;
Name = "Trousers/Pyjamas";
Wash = 20;
"Wash_Iron" = 30;
id = 5;
},
{
"Dry_cleaning" = 70;
Iron = 7;
Name = Jeans;
Wash = 20;
"Wash_Iron" = 29;
id = 6;
},
{
"Dry_cleaning" = 150;
Iron = 5;
Name = Blazer;
Wash = 25;
"Wash_Iron" = 19;
id = 7;
},
{
"Dry_cleaning" = 100;
Iron = 6;
Name = "Leather_Jacket";
Wash = 30;
"Wash_Iron" = 36;
id = 8;
}
}
Here this is my code

Answer 2

You are following the wrong way to do this. Just use an array which have initial value 0 on all index and set array value to label in cellForRowAtIndexPath than update the array index value on click on stepper event than reload your table with updated array.
