Blurring backgrounds in SwiftUI offers a powerful tool for creating visually appealing and user-friendly interfaces. Here’s an in-depth exploration of the two main methods and considerations for each:

• Customization:
  - radius: Controls blur intensity (higher values = stronger blur).
  - opaque: Determines transparency (default is false for non-transparent blur).
• Example:

Text("Hello, world!")
    .background(Color.black)

• Offers basic control over blur intensity and transparency.

Disadvantages:

• Limited compared to Material in terms of styles and automatic dark mode adaptation.
• Performance impact can be higher due to custom rendering.

Material Type (iOS 15+):

• Richer Experience: Provides built-in blur effects adhering to HIG, adapting to dark mode.
• Five Defined Styles:
