BehaviourRelay variable remove duplicates

Just inherited this code base and I'm not quite familiar with RxSwift. I've done some reading but cannot find a solution to my problem.

We have a variable declared. This saves information from a network call, and then is being used to load information to a collection view. Therefore the collection view is showing multiple similar items

var allPhotos = BehaviorRelay<[Photo]>.init(value: [])

How do I convert it to a set to remove duplicates?

Solution

  • Try this:

    let filteredPhotos = allPhotos.asObservable().map { Array(Set($0)) }

    PS: Make sure Photo conforms to Hashable
