I am working on an app that will allow users to share or save the view via a share sheet. To capture the view I am using the ImageRenderer. When I go to click on the share button, it does not work and says, "Unable to render flattened version of PlatformViewControllerRepresentableAdaptor<MulticolumnSplitViewRepresentable<ModifiedContent<Element, NavigationColumnModifier>, Never, _UnaryViewAdaptor>>." When I go to the issues it will say, "Context in environment is not connected to a persistent store coordinator: <NSManagedObjectContext: 0x6000014851e0>." How can I fix this.
This is the code.
struct DividendView: View {
@Environment(\.managedObjectContext) var moc
@FetchRequest(sortDescriptors: [
SortDescriptor(\.stock_name)
]) var dividends: FetchedResults<Dividend>
@State private var showingAddScreen = false
@State private var showingShare = false
// @EnvironmentObject var vm = ViewModel()
@State private var renderedImage: Image?
@State private var selectedName: String?
@State private var expanded: Bool = false
let dividend: Dividend
// @State private var items: [Any] = []
// @State private var sheet: Bool = false
// let columns = [GridItem(.fixed(50)), GridItem(.fixed(50)), GridItem(.fixed(50)), GridItem(.fixed(50)), GridItem(.fixed(50))]
