EditButton, PasteButton, Rename Button in SwiftUI.

SwiftUI provides several built-in buttons that facilitate common actions like editing, pasting, and renaming directly within your views. Understanding how to implement EditButton, PasteButton, and RenameButton can greatly improve the usability and efficiency of your SwiftUI applications. Let’s dive into each button’s functionality with unique examples and best practices.

Using EditButton for List Management

The EditButton in SwiftUI is used to toggle the editing mode of list views or any other container that supports editing. This allows users to easily perform actions such as deleting or moving items within a list.

Example: Managing a Fruit List with EditButton

import SwiftUI

struct FruitListView: View {
    @State private var fruits = ["Apple", "Banana", "Papaya", "Mango"]
    
    var body: some View {
        NavigationStack {
            List {
                ForEach(fruits, id: \.self) { fruit in
                    Text(fruit)
                }
                .onDelete(perform: { indices in
                    fruits.remove(atOffsets: indices)
                })
                .onMove(perform: { indices, newOffset in
                    fruits.move(fromOffsets: indices, toOffset: newOffset)
                })
            }
            .navigationTitle("Fruits")
            .toolbar {
                EditButton()
            }
        }
    }
}

What’s Happening:

• A list of fruits allows users to delete or reorder items when in edit mode.
• The EditButton toggles the list’s edit mode, showing “Edit” or “Done” based on the current state.

Using PasteButton for Content Importing

PasteButton offers a seamless integration for pasting content from the clipboard into your app. It’s highly customizable and can handle various data types that conform to the Transferable protocol.

Example: Pasting Text with PasteButton

import SwiftUI

struct PasteTextView: View {
    @State private var pastedText: String = ""
    
    var body: some View {
        VStack {
            PasteButton(payloadType: String.self) { strings in
                pastedText = strings.first ?? ""
            }
            Text("Pasted content: \(pastedText)")
                .padding()
        }
        .frame(width: 300, height: 100)
        .border(Color.gray)
    }
}

What’s Happening:

• A PasteButton is set up to accept strings from the clipboard.
• When content is pasted, it is displayed in a text view below the button.

Using RenameButton for Inline Renaming

In this example, RenameButton is used to trigger renaming directly within a TextField. The button is integrated into the navigation bar for clear accessibility, ensuring it is contextually appropriate.

Example: Renaming in a Context Menu

struct RenameButtonExample: View {
   
    @State private var name = "John Doe"  // Example default name
    @FocusState private var isNameFocused: Bool

    var body: some View {
        
        NavigationStack {
            VStack {
                Text("Profile Name:")
                    .font(.headline)
                    .padding(.top, 20)
                
                TextField("Enter new name", text: $name)
                    .textFieldStyle(RoundedBorderTextFieldStyle())
                    .focused($isNameFocused)
                    .padding()
                    .contextMenu {
                        Button {
                            self.isNameFocused = true
                        } label: {
                            Label("Rename", systemImage: "pencil")
                        }
                    }
                
                Spacer()
            }
            .padding()
            .navigationTitle(name)
            .toolbar {
                ToolbarItem(placement: .navigationBarTrailing) {
                    RenameButton()
                        .renameAction {
                            self.isNameFocused = true
                        }
                }
            }
            
        }
    }
}

What’s Happening:

• What’s Happening:
  • User Interface: The user is presented with a text field to enter or edit their name.
  • Focus Management: The @FocusState is used to control the focus of the TextField.
  • Rename Button: The RenameButton is placed in the navigation bar. When tapped, it triggers the renaming action by setting focus to the text field (isFocused = true).

Conclusion
