Filtering String from Firestore database sends an error on SwiftUI - filter

Question

I'm working on implementing a search for a movies database stored in firestore using SwiftUI. I've tried doing filtering the movie names by the entered text as follows:
#ObservedObject var movies = getMoviesData()
...
ForEach(self.movies.datas) { movies in
ForEach(movies.title.filter({"\($0)".contains(searchText.lowercased()) || searchText.isEmpty})) { item in
if let url = URL(string: movies.img) {
AnimatedImage(url: url)
.resizable()
.frame(width: bounds.size.width / 2 - 0.6, height: bounds.size.height / 2 - 0.2)
}
}
.animation(.spring())
}
...
struct movies : Identifiable {
var id: String
var title: String
var img: String
var video: String
var description: String
var genre: String
}
class getMoviesData : ObservableObject{
#Published var datas = [movies]()
private var db = Firestore.firestore()
func fetchData(){
db.collection("movies").addSnapshotListener{ (querySnapshot, error) in
guard let mov = querySnapshot?.documents else{
print("No movies")
return
}
self.datas = mov.map{(queryDocumentSnapshot) -> movies in
let data = queryDocumentSnapshot.data()
let id = data["id"] as? String ?? ""
let title = data["title"] as? String ?? ""
let img = data["img"] as? String ?? ""
let video = data["video"] as? String ?? ""
let description = data["description"] as? String ?? ""
let genre = data["genre"] as? String ?? ""
return movies(id: id, title: title, img: img, video: video, description: description, genre: genre)
}
}
}
}
However, I'm receiving the following error on the second ForEach statement:
Referencing initializer 'init(_:content:)' on 'ForEach' requires that 'String.Element' (aka 'Character') conform to 'Identifiable'
Movies.title represents a String output of each movie identified in the ForEach statement. How should I filter movies.title against the provided search text without invoking this error?

Answer 1

I am little confused about your use of variable names.
ForEach(movies.title.filter({"\($0)".contains(searchText.lowercased()) || searchText.isEmpty})) { item in
}
}
In the above code movies.title is very misleading. Is there a title property on movies array. If you need to filter, you can perhaps check out the sample code below:
struct Movie {
let title: String
}
let movies = [Movie(title: "Spiderman"), Movie(title: "Batman"), Movie(title: "Superman")]
let searchWord = "batman"
let filteredMovies = movies.filter { movie in
return movie.title.lowercased().contains(searchWord.lowercased())
}
print(filteredMovies)
