20. Request struct AlgoliaFeedRequest: AlgoliaRequestProtocol { typealias HitType = Algolia.Feed var indexName: String { return "feed" } var query: AlgentQuery { let query = AlgentQuery() return query } }
21. Read // search from algolia using Algent // Result<Response<Response<Request.HitType>, Error> Algent.shared.search(request: AlgoliaFeedRequest()) Firebase.Post.databaseRef .child(feed.objectID) .child(“likes/count") .observe(.value) { [weak self] snapshot in if snapshot.exists() { self?.likeCountString.value = "\(snapshot.value as?
