How to check if already custom object exist in array?

Question

I have a array of object of custom class. My class is Person. So i want to check if arrPerson contains an object then it should not be added again in array.

Here is my code

for value in data {

    if self.arrPerson.contains(where: {($0.id != value.id)}){
        self.arrPerson.append(value)
    }
}

Please tell me how can i check if object of custom class already added then it should not be added again

if you don't want to compare any property you can just compare the object {($0 == value)} — Surya Subenthiran

only write if !self.arrPerson.contains(where: {($0.id == value.id)}){ self.arrPerson.append(value) }

You can use "set" instead of array it will avoid the duplicate values.
