How do you create a video intro to an app with the control bar?

To create a video intro to an app with a control bar, you can utilize the new SwiftUI APIs to customize the window and toolbar elements. Here's a step-by-step guide based on the session "Tailor macOS windows with SwiftUI":

1. Create a Window Group: Start by creating a window group with a content view. This will serve as the main window for your video intro.

2. Customize the Toolbar: Use the toolbar modifier to add or remove toolbar items. You can also use the toolbarBackground and toolbarBackgroundVisibility modifiers to customize the appearance of the toolbar.

3. Highlight the Video Content: To emphasize the video content, you can remove the title and toolbar background. This can be done using the toolbarRemoving and toolbarBackgroundVisibility modifiers.

4. Add Video Player: Integrate a video player within the content view of the window. This will be the main element of your video intro.

5. Refine Window Behaviors: Customize the window behaviors to match the design of your app. For example, you can disable the zoom and minimize controls if the content has a fixed size.

Here is a relevant segment from the session:

"It is created from a window group with a content view. Right now, the window shows the toolbar and title. My design features a large image below them. To highlight the image, I remove both the title and the toolbar background using the toolbar removing modifier and the toolbar background visibility modifier. And now the large image extends to the top edge of the window." - Tailor macOS windows with SwiftUI
