I would like to do a NavigationLink from List to a Detail-
View (change the Stock-Datails). I know how to do the NavigationLink but not how to hand over the detail-Record of the list.
List sample - https://developer.apple.com/forums/content/attachment/b29fa9f2-7243-41f2-b75f-8961c9b79c44
I would appriciate to see a sample. Those e.g. of "Landmarks" do not have Core-Date.
Thank you in advance

I am new here and wanted to create code and program for my personal use.
I chose a new Project (IOS App) with Xcode 12.2 and then chose SwiftUI and "Use Core Data". It will generate a project with an Entity -item- that shows errors and can't be extended further. New Attritbutes can be typed in but can't be addressed in the code (Unknown).
Are there any hints? Can't you read somewhere how the correct form of CoreData is?
Thanks in advance.

Is there anybody who can show me how to use NumberFormatter.
I would like to use it to transform input from TextField into NSNumber.
