Hi Just getting started with CoreData. I have two entities - Project + Element. These have a one to many relationship. eg each project can have many elements.

I have three views. Project List View - A list of my project with a Navigation Link to Project Detail.

Project Detail View- Shows detail for a chosen project with a list of elements for that project and a navigation link to Add Element View.

Add Element View - Allows you to add a new element and name it.

On the whole my views work. I can add an element and when I navigate back to detail it appears in the list. The issue is that the element list shows all elements for all projects regardless of which project I'm viewing.

List {
                                ForEach(elements, id: \.self) { element in
                                        VStack {
                                            HStack {
                                                Text(element.elementName ?? "Unknown")
                                            }
                                            .font(Font.headline.weight(.bold))
                                        }
                                }// END OF FOR EACH
                                .onDelete(perform: deleteElements)
                            }// END OF LIST

How do I change the list to only show elements forthe current Project??

If you set up a relationship in CoreData between Project and Element then your Project should have a variable called elements. This is usually a (NS)Set. So basically, you need to reference your project in your detail view and use project.elements instead of all elements.
