what is the difference between safeAreaPadding and contentMargins in SwiftUI?

In SwiftUI, safeAreaPadding and contentMargins serve different purposes for managing the layout of your views.

safeAreaPadding

• Purpose: Ensures that your content does not overlap with system UI elements or device-specific features like rounded corners, the home indicator, or the dynamic island on iPhone.
• Usage: Typically used to adjust the layout so that important UI elements remain visible and accessible.
• Example: You might use safeAreaPadding to ensure that a button is not obscured by the home indicator on an iPhone.

contentMargins

• Purpose: Provides a consistent margin around the content within a view, ensuring that the content is not too close to the edges of the view.
• Usage: Used to create a visually appealing layout by adding space around the content.
• Example: You might use contentMargins to ensure that text within a view has some padding around it, making it easier to read and more aesthetically pleasing.

Context from WWDC Sessions

• In the session Design advanced games for Apple platforms, it is mentioned that safe areas are regions of the display where you can safely put UI so that it doesn't overlap with hardware or software features.
• In the session What’s new in watchOS 11, content margins are preconfigured to ensure that the content is visually consistent and does not get too close to the edges.
