Trouble Reading and Formatting Date - swiftui

Question

I'm attempting to read some data from CoreData into a standard list and have trouble reading and formatting the date. I appear to be way off in the weeds! I have the error "Value of type 'Date?' has no member 'getFormattedDate'" where I'm trying to display the date and the error "Cannot convert value of type 'listView' to expected argument type 'Date'" at the last line of the getFormattedDate function.
struct listView: View {
#Environment(\.managedObjectContext) private var viewContext
let categories = ["AAA", "BBB","CCC","DDD"]
#FetchRequest(
entity: CurrTrans.entity(),
sortDescriptors: []
) var currTrans: FetchedResults<CurrTrans>
var body: some View {
List {
ForEach(currTrans, id: \.self) { item in
VStack {
let date = item.entryDT
Text(date.getFormattedDate())
// display category
if item.entryCat != nil {
Text("Category: \(categories[Int(item.entryCat)])")
} else {
Text("")
// display description
if item.entryDsc != nil {
Text("\(item.entryDsc!)")
} else {
Text("")
}
}
}
}
func getFormattedDate() -> String {
let dateformat = DateFormatter()
dateformat.dateFormat = "d MMM HH:mm"
return dateformat.string(from: self)
}
}
}

#objc(Transaction)
public class Transaction: NSManagedObject {
static let categoryStringsByCategoryID = ["AAA", "BBB","CCC","DDD"]
func categoryString() -> String{
return Transaction.categoryStringsByCategoryID[self.categoryID]
}
}
struct ListView: View {
#Environment(\.managedObjectContext) private var viewContext
#FetchRequest(sortDescriptors: []) var transactions: FetchedResults<Transaction>
var body: some View {
List {
ForEach(transactions) { transaction in
VStack {
Text("\(transaction.timestamp!, formatter: transactionFormatter)")
// display category
Text("Category: \(transaction.categoryString)")
// display description
Text("\(transaction.entryDescription ?? "")")
}
}
}
}
}
private let transactionFormatter: DateFormatter = {
let formatter = DateFormatter()
formatter.dateStyle = .short
formatter.timeStyle = .medium
return formatter
}()
