How do I make a Searchbar on text in Xcode 12.2 beta 2, without reverting to the complicated Swift code? The code below compiles and successfully displays all the animals, but the second part of the terneray operator does not filter a search of any kind. Much obliged,

Bruckner

AnimalModel.swift:

import SwiftUI

struct Animal: Codable, Identifiable, Hashable {
    let id: String
    let name: String
    let headline: String
    let description: String
    let link: String
    let image: String
    let gallery: [String]
    let fact: [String]
}

ContentView.swift:

import SwiftUI

struct ContentView: View {
    // MARK: - PROPERTIES
    @State private var searchText: String = ""
    //@State private var text: String = ""
    let animals: [Animal] = Bundle.main.decode("animals.json")

    //@ObservedObject var searchBar: SearchBar = SearchBar()

    // MARK: - BODY

    var body: some View {
        NavigationView {
            ScrollView {
                HStack {
                    TextField("Search animals here", text: $searchText)
                }
                .padding()
                .background(Color(.systemGray5))
                .cornerRadius(8)
                .padding(.horizontal)

                ForEach(animals.filter({_ in 
                                        self.searchText.isEmpty ? true :
                                            "$0".lowercased().contains(searchText.lowercased())})
                )  {
                    animal in
                    HStack {
                        Image(animal.image)
                            .resizable()
                            .scaledToFit()
                            .frame(width: 80, height: 80)

                        Text(animal.name)
                            .font(.headline)
                            .fontWeight(.bold)
                        Spacer()
                    }//: HSTACK
                    .padding()
                    Divider()
                }//: LOOP
            }
            .navigationBarTitle("African Animals")
        }
    }
}

hi Bruckner,

you wrote "$0".lowercased() in the tail of the ternary. did you mean $0.lowercased() ?

hope that helps,

If we remove the quotes, we get the error Anonymous closure arguments cannot be used inside a closure that has explicit arguments. I'm also looking now (March 2021) for a nice code for the SwiftUI 2.0 search bar with a magnifying glass picture, but still haven't found any nice working way.

While it not the in the title but the code shows a search bar, from WWDC20
