FileRepresentation.importing's 'receivedData' is already deleted. when I use.
import CoreTransferable
struct Movie: Transferable {
let url: URL
static var transferRepresentation: some TransferRepresentation {
FileRepresentation(contentType: .movie) { movie in
SentTransferredFile(movie.url)
} importing: { receivedData in
let fileName = receivedData.file.lastPathComponent
let copy: URL = FileManager.default.temporaryDirectory.appendingPathComponent(fileName)
try FileManager.default.copyItem(at: receivedData.file, to: copy)
return .init(url: copy)
}
}
}

https://developer.apple.com/wwdc22/10054 doesn't explain multi NavigationLink in one cell.
class FinalBluePrint: ObservableObject {
@Published var currentGrade: Double = 5;
@Published var desiredGrade : Double = 0;
@Published var finalWeight : Double = 0;
var finalNeededGrade : Double {
let desiredGrade = self.desiredGrade;
let currentGrade = self.currentGrade;
let finalWeight = self.finalWeight;
let finalNeededGrade = (desiredGrade - currentGrade * (100 - finalWeight)) / finalWeight;
return finalNeededGrade
}
}
struct ContentView: View {
@StateObject var final = FinalBluePrint()
var body : some View {
NavigationView {
VStack {
TextField("Current Grade", value: $final.currentGrade, format: .number).keyboardType(.decimalPad);
TextField("Desired Grade", value: $final.desiredGrade, format: .number).keyboardType(.decimalPad);
TextField("Final Weight", value: $final.finalWeight, format: .number).keyboardType(.decimalPad);
Text(final.currentGrade, format: .number);
Text(final.finalNeededGrade, format: .number);
}
}
}
}
List in List does not work well.
You should change code like below code
List {
Button("ADD") {
}
Section {
ForEach(data) { datum in
}
}
}

I face to same issue in Playground. Normal Project can compile it.
