Using Generic SwiftData Modules
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 == "+" ? "Positive" : "Negative") } .font(.caption2) .foregroundStyle(lastCharacter == "+" ? .green : .pink) } } } }

Using truncationMode
Hi, The example that Apple shows in link below doesn't show how truncationMode works, because the text get truncated anyway when its length it more than frame height so what's the use of truncationMode ? https://developer.apple.com/documentation/swiftui/view/truncationmode(_:) -- Kind Regards
