The ProgressView in SwiftUI is a built-in component used to display the progress of a task to the user. It is a UI element that can be customized with different styles, and it can be used in various contexts such as loading screens, file uploads, and downloads.

Let’s look in-depth at how to use ProgressView in SwiftUI.

Creating a Basic ProgressView

To create a basic ProgressView, you can use the ProgressView initializer and set the progress value between 0 and 1. Here is an example:

struct ContentView: View {
    @State var progressValue: Float = 0.5

    var body: some View {
        ProgressView(value: progressValue)
    }
}

In the above code, we have created a ProgressView with a default style, and we have set the progress value to 0.5. The progress value can be updated dynamically by changing the value of the progressValue state variable.

Customizing the ProgressView Style

You can customize the appearance of the ProgressView by changing the style. SwiftUI provides three built-in styles for the ProgressView: DefaultProgressViewStyle, CircularProgressViewStyle, and LinearProgressViewStyle.
