Compare 2 Results by object of selected index of filteredList swift4












-1















I have 2 lists of same custom object i.e. News



class News: Object {
@objc dynamic var title: String?
@objc dynamic var date: Date?
@objc dynamic var contentUrl: String?
}


and 2 lists are



var filteredList: Results<News>! = nil
var newsList: Results<News> {
get {
return realm.objects(News.self).sorted(byKeyPath: "date", ascending:
false)
}
}


I am filtering the list and the filtered data is storing in filteredList.
Now I want to send the IndexPath of newsList to the next VC. When I search in the list, filteredList is appending to the tableView which is absolutely correct. When I selecting row from filteredList it is giving index of filteredList. Now though user selects filteredList's index , it should compare with the object of newList and should return that indexPath /index of newsList



I have done it by my own way



override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: 
IndexPath) {
searchController.dismiss(animated: true, completion: nil)
var sendIndex : IndexPath?
let layout = UICollectionViewFlowLayout()
layout.scrollDirection = .horizontal
if !searchBarIsEmpty(){
for (index,news) in newsList.enumerated(){
if news.title == filteredList[indexPath.row].title{
sendIndex = IndexPath(row: index, section: 0)
}
}
}else{
sendIndex = indexPath
}
if let index = sendIndex{
let vc = NewsDetailsVC(collectionViewLayout: layout)
vc.tappedIndex = index
vc.title = "News Details"
vc.isSelectNews = true
self.navigationController?.pushViewController(vc, animated: true)
}

}


but it can be more optimise.. Please suggest some logic of optimisation

Here's a one-liner for finding the index to be sent.



if !searchBarIsEmpty() {
sendIndex = IndexPath(row: newsList.firstIndex(where: { $0.title == filteredList[indexPath.row].title }), section: 0)
}


Note: title is assumed to be the primary key. Compare with the appropriate primary key.
