To determine the screen resolution, you can use different methods depending on the context and platform you are working with. Here are some relevant insights from the WWDC sessions:

  1. Using VisionOS:

    • In the session Bring your iOS or iPadOS game to visionOS, it is mentioned that you can use the resolution component to get an approximation of the size in pixels that a 1-meter cube would take on the screen at a 3D location. This can help you understand the screen resolution dynamically as the camera moves.
  2. Using SwiftUI for macOS:

    • In the session Tailor macOS windows with SwiftUI, you can specify the initial placement of a newly created player window using the default window placement modifier. This involves querying the size of the content and the context value with information about the display, which can help you determine the screen resolution.
  3. Using ScreenCaptureKit:

    • In the session Capture HDR content with ScreenCaptureKit, you can specify different resolutions or pixel formats for capturing screen content. This involves configuring the SC stream configuration to customize the stream output, which can give you insights into the screen resolution.
  4. General Design Considerations:

    • In the session Design advanced games for Apple platforms, it is emphasized to make sure your UI is legible across different screen sizes. This involves understanding the screen resolution to ensure text and UI elements are appropriately sized.
