Introduction
Creating a ListView with Custom Cells is a common task in iOS app development. Custom Cells give you more control over the look and feel of the list items, allowing you to create a more tailored user experience. In this tutorial, we will create a ListView with Custom Cells containing a title, subtitle, image, and button. The ListView will be wrapped inside a Navigation Bar to give users easy access to other parts of the app.
Prerequisites
This tutorial assumes you have a basic understanding of SwiftUI and Xcode. You should also have a development environment set up and running.
Step 1: Create a Custom Cell View
The first step is to create a Custom Cell View that will display the title, subtitle, image, and button.
struct CustomCellView: View {
let title: String
let subtitle: String
let image: String
let buttonAction: () -> Void
var body: some View {
HStack {
Image(image)
.resizable()
.frame(width: 50, height: 50)
.cornerRadius(10)
VStack(alignment: .leading) {
Text(title)
.font(.headline)
Text(subtitle)
.font(.subheadline)
}
Spacer()
Button(action: buttonAction) {
Text("Explore")
.padding(.horizontal, 10)
.padding(.vertical, 5)
.background(Color.blue)
.foregroundColor(Color.white)
.cornerRadius(5)
}
}
.padding()
}
}
In this code, we define a CustomCellView that takes in a title, subtitle, and imageName. We then create a HStack containing an Image view, a VStack containing the title and subtitle text, a Spacer to push the button to the right, and finally, a Button with an action and label.
Step 2: Create a ListView
Next, we create a ListView that will display a list of Custom Cells.
struct ListView: View {
let items = [
(title: "Item 1", subtitle: "Subtitle 1", image: "image1"),
(title: "Item 2", subtitle: "Subtitle 2", image: "image2"),
(title: "Item 3", subtitle: "Subtitle 3", image: "image3"),
(title: "Item 4", subtitle: "Subtitle 4", image: "image4"),
(title: "Item 5", subtitle: "Subtitle 5", image: "image1")
]
var body: some View {
NavigationView {
List {
ForEach(items, id: .title) { item in
NavigationLink(destination: DetailView(title: item.title, subtitle: item.subtitle, image: item.image)) {
CustomCellView(title: item.title, subtitle: item.subtitle, image: item.image){
print("Button tapped for item: (item.title)")
}
}
}
}
.navigationBarTitle("Your Past Searches")
}.ignoresSafeArea()
}
}
In this code, we define a ListView that contains a List. We then use a ForEach loop to loop through our items array and create a CustomCellView for each item. We wrap each `CustomCell View in a NavigationLink that links to a DetailView passing the title, subtitle, and imageName as parameters.
Step 3: Create a DetailView
The DetailView will display the details of a selected item.
struct DetailView: View {
let title: String
let subtitle: String
let image: String
@Environment(.presentationMode) var presentationMode: Binding
var body: some View {
VStack {
Image(image)
.resizable()
.frame(width: 150, height: 150)
.cornerRadius(20)
Text(title)
.font(.largeTitle)
Text(subtitle)
.font(.title)
Button(action: {
presentationMode.wrappedValue.dismiss()
}) {
Text("Back")
.padding(.horizontal, 10)
.padding(.vertical, 5)
.background(Color.blue)
.foregroundColor(Color.white)
.cornerRadius(5)
}
}
.padding()
}
}
In this code, we define a DetailView that takes in the title, subtitle, and imageName. We then create a VStack containing an Image view, a Text view for the title, a Text view for the subtitle, and a back button to push the view back to previous screen.
Step 4: Add Navigation Links to ListView
To link our ListView to our DetailView, we need to wrap our ListView in a NavigationView.
struct ContentView: View {
var body: some View {
NavigationView {
ListView()
.navigationTitle("List View")
}
}
}
In this code, we define a ContentView that contains a NavigationView wrapping our ListView. We also set the navigation bar title to "List View".
Step 5: Add a Navigation Bar Title
Finally, we can add a navigation bar title to our DetailView.
struct DetailView: View {
let title: String
let subtitle: String
let image: String
@Environment(.presentationMode) var presentationMode: Binding
var body: some View {
VStack {
Image(image)
.resizable()
.frame(width: 150, height: 150)
.cornerRadius(20)
Text(title)
.font(.largeTitle)
Text(subtitle)
.font(.title)
Button(action: {
presentationMode.wrappedValue.dismiss()
}) {
Text("Back")
.padding(.horizontal, 10)
.padding(.vertical, 5)
.background(Color.blue)
.foregroundColor(Color.white)
.cornerRadius(5)
}
}
.padding().navigationTitle(title)
}
}
In this code, we add a .navigationTitle modifier to our VStack to set the navigation bar title to the title of the item.

Q: Can I customize the navigation bar further?
A: Yes, you can customize the navigation bar by adding modifiers such as .navigationBarColor, .navigationBarTitleDisplayMode, or .navigationBarItems.
Conclusion
In this tutorial, we created a ListView with Custom Cells containing a title, subtitle, image, and button. The ListView was wrapped inside a Navigation Bar to give users easy access to other parts of the app. We also created a DetailView to display the details of a selected item. By following the steps outlined in this tutorial, you can create your own ListView with Custom Cells and Navigation Bar in SwiftUI.
