Yes, groupArray is a dictionary. The complete code is:
struct ResultView: View {
@State var websites : [Website]
@Binding var text : String
@State var groupedArray : [String: [Website]] = [:]
var body: some View {
List{
ForEach(groupedArray.keys.sorted().filter{
text.isEmpty || $0.contains(text)
}, id: \.self){key in
Section(header: Text(key)) {
ForEach(groupedArray[key]!, id: \.self){website in
NavigationLink(
destination: WebView(website: website, url: URL(string: website.url)),
label: {
Text(website.name)
Spacer()
if website.image != ""{
RemoteImage(url: website.image).frame(width: 25, height: 25, alignment: .center)
}else{
Loader()
}
})
}
}
}
}.frame(width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height, alignment: .center)
.navigationBarTitle("Results")
.colorScheme(.light)
.onAppear {
groupedArray = Dictionary(
grouping: websites,
by: {$0.name.first?.uppercased() ?? ""}
).mapValues{$0.sorted()}
}
}
}
struct Loader : UIViewRepresentable{
func makeUIView(context: UIViewRepresentableContext<Loader>) -> UIActivityIndicatorView {
let indicator = UIActivityIndicatorView(style: .large)
indicator.startAnimating()
return indicator
}
func updateUIView(_ uiView: UIActivityIndicatorView, context: UIViewRepresentableContext<Loader>) {
}
}
I have this method from a tutorial, but there wasn't the filter method so I wrote it behind the keys in the ForEach. I don't know if thats right. The content is from a database but the array looks like this:
@State var websites = [Website] = [Website(url: "https://www.apple.com/", name: "Apple", image: "Apple.png" , calls: 0), Website(url: "https://www.amazon.com/", name: "Amazon", image: "Amazon.png" , calls: 0)]
Is that all you need to know?
