Hi, I have the view below that I want it to get any sort of SwiftData model and display and string property of that module, but I get the error mentioned below as well, also the preview have an error as below, how to fix it ? I know its little complicated. Error for the view GWidget " 'init(wrappedValue:)' is unavailable: The wrapped value must be an object that conforms to Observable " Error of preview " Cannot use explicit 'return' statement in the body of result builder 'ViewBuilder' " 3, Code #Preview { do { let configuration = ModelConfiguration(isStoredInMemoryOnly: true) let container = try ModelContainer(for: Patient.self, configurations: configuration) let example = Patient(firstName: "Ammar S. Mitoori", mobileNumber: "+974 5515 7818", homePhone: "+974 5515 7818", email: "ammar.s.mitoori@gmail.com", bloodType: "O+") // Pass the model (Patient) and the keyPath to the bloodType property return GWidget(model: example, keyPath: \Patient.bloodType) .modelContainer(container) } catch { fatalError("Fatal Error") } } 4. Code for the Gwidget View ```import SwiftUI import SwiftData struct GWidget<T>: View { @Bindable var model: T var keyPath: KeyPath<T, String> // Key path to any string property // Variables for the modified string and the last character var bloodTypeWithoutLast: String { let bloodType = model[keyPath: keyPath] return String(bloodType.dropLast()) } var lastCharacter: String { let bloodType = model[keyPath: keyPath] return String(bloodType.suffix(1)) } var body: some View { VStack(alignment: .leading) { Text("Blood Type") .font(.footnote) .foregroundStyle(sysPrimery07) HStack (alignment: .lastTextBaseline) { Text(bloodTypeWithoutLast) .fontWeight(.bold) .font(.title2) .foregroundStyle(sysPrimery07) VStack(alignment: .leading, spacing: -5) { Text(lastCharacter) .fontWeight(.bold) Text(lastCharacter == "+" ?

Hi, Suppose I want to create an School management App that have little complex views so I need a three versions of each view one for Mac and one for iPadOS and one for iOS, cause using platform detector on same view and adjusting layout will make things messy. So what's the best way to achieve that ? Separate project to each platform ? maybe Targets which I still don't understand cause modifying a view in any target will be reflected to other targets so what's the best practice here ? Im working with SwiftUI Kind Regards

Hi, Before the iOS 17.2 update the saving behavior of SwiftData was very straightforward, by default it saves to persistence storage and can be configured to save in memory only. Now it saves to memory by default and to make it save to persistence storage we need to use modelContext.Save(). But if we don't quit the App the changes will be saved after a while to persistence storage even without running modelContext.Save() ! How confusing can that be for both developer and the user ! Am I missing something here ? -- Kind Regards
