I also experienced a similar problem in the past.
How about trying this way?
class SaveWords: ObservableObject {
static let shared = SaveWords()
// others...
}
import SwiftUI
struct SearchView: View {
@State private var searchText = ""
var save = SaveWords.shared
@State var heart: String?
@State var disappear = false
@State var done = true
var body: some View {
NavigationView {
VStack {
if !disappear {
SearchBarView(text: $searchText)
Spacer()
}
if searchText != "" {
List(.constant(Array(FetchWord.getWordFromStart(start: searchText)).prefix(10).map {Word(word: $0.1)})) { suggestion in
NavigationLink(destination: suggestion.IPA.wrappedValue == "error" ? AnyView(EmptyView()) : AnyView(PracticeView(wordSheet: suggestion)
.onAppear {
disappear = true
if done {
SaveWords.file = "Favorites"
DispatchQueue.main.async {
Task {
try? await save.load()
heart = save.words.contains(suggestion.wrappedValue) ? ".fill" : ""
}
}
}
}
.onDisappear {
disappear = false
Task {
SaveWords.file = "History"
try? await save.load()
if save.words.first != suggestion.wrappedValue {
save.words.insert(suggestion.wrappedValue, at: 0)
try? await save.save()
}
}
}
.toolbar {
ToolbarItem(placement: .navigationBarTrailing) {
Button(action: {
SaveWords.file = "Favorites"
done = false
if heart == "" {
heart = ".fill"
DispatchQueue.main.async {
Task {
try? await save.load()
if !save.words.contains(suggestion.wrappedValue) {
save.words.insert(suggestion.wrappedValue, at: 0)
try? await save.save()
}
}
}
} else {
heart = ""
DispatchQueue.main.async {
Task {
try? await save.load()
try? await save.delete(wordToDelete: suggestion.wrappedValue)
try? await save.save()
}
}
}
done = true
}, label: {
Image(systemName: "heart" + (heart ?? ""))
})
}
})
) {
if suggestion.IPA.wrappedValue != "error" {
CardView(wordSheet: suggestion)
}
}
}
}
}
Spacer()
}
}
}
