Introduction

When building an app with SwiftUI, it's common to encounter the need to customize the navigation bar, particularly the title. In this article, we'll explore how to create a custom title in the navigation bar in SwiftUI. We'll cover the basics of navigation bars, how to create a custom title, and provide examples to help you get started.

Understanding Navigation Bars in SwiftUI

In SwiftUI, navigation bars are used to display a title and navigation buttons. By default, the title is displayed in the center of the navigation bar. However, you can customize the title to fit your app's design and branding.

Creating a Custom Title in SwiftUI

To create a custom title in SwiftUI, you can use the navigationBarTitle modifier. This modifier allows you to specify a custom title for the navigation bar.

struct VehiclePositionView: View {
    var body: some View {
        NavigationView {
            Text("Custom Title")
                .navigationBarTitle("Custom Title")
        }
    }
}

In this example, we're using the navigationBarTitle modifier to set the custom title to "Custom Title".

Customizing the Navigation Bar Title

You can also customize the navigation bar title by using the navigationBarTitleDisplayMode modifier. This modifier allows you to specify how the title is displayed in the navigation bar.

struct VehiclePositionView: View {
    var body: some View {
        NavigationView {
            Text("Custom Title")
                .navigationBarTitleDisplayMode(.inline)
        }
    }
}

In this example, we're using the navigationBarTitleDisplayMode modifier to display the title inline.

Adding a Custom Title with a Subtitle

You can also add a custom title with a subtitle by using the navigationBarTitle modifier with a string that contains both the title and subtitle.

struct VehiclePositionView: View {
    var body: some View {
        NavigationView {
            Text("Custom Title")
                .navigationBarTitle("Custom Title | Subtitle")
        }
    }
}

In this example, we're using the navigationBarTitle modifier to set the custom title to "Custom Title | Subtitle".

Using a View as the Navigation Bar Title

You can also use a view as the navigation bar title by using the navigationBarTitle modifier with a view.

struct CustomTitleView: View {
    var body: some View {
        Text("Custom Title")
            .font(.largeTitle)
    }
}
struct VehiclePositionView: View 
var body some View {
NavigationView {
Text("Custom Title")
.navigationBarTitle(CustomTitleView())

}
}

In this example, we're using the navigationBarTitle modifier to set the custom title to a view that contains a large title text.
