How to remove common items from two struct arrays in Swift

Question

In my app I have two struct arrays and I want to remove common items from one of them. My struct:

struct PeopleSelectItem {
    var name = \"\"
    var id =          


        

Answer 1

• Get an array of all ids in selectedPeople

  let selectedPeopleIDs = selectedPeople.map { $0.id }
  

• Filter the items whose id is not in the array

  let filteredPeople = people.filter { !selectedPeopleIDs.contains($0.id) }
