If you have a tiered playlist structure, you'll want to add images to all playlists that will be present within your app. ![]() Launch images are static and don’t include layers. It appears instantly and is quickly replaced with the first screen of your app. Please note this layer cannot be transparent.Ī splash screen displays when your app starts up. We suggest using a simple, dark background (dark enough for light font to be legible on) OR a simple, light background (light enough for dark font to be legible on). This will be the background for your Apple TV channel. 4640 x 1440px, JPEG (top shelf wide 2x size).This is a great opportunity for added visibility. The top shelf image will be used when the user has placed your app in the top row of the Home screen. Small front 2x size: 8 00 x 480px, PNG with transparency (safe zone approx.Small front: 400 x 240px, PNG with transparency (safe zone = 370 x 222px or see image below).Large front: 1280 x 768px, PNG with transparency.Large back: 1280 x 768px, PNG (safe zone approx. ![]() Please note the background layer cannot be transparent. If your icon includes text, bring it to the front so it’s not hidden by other layers when the parallax effect occurs. ![]() If your icon includes a logo, separate it from the background. When uploading to Zype you will upload each layer separately.Ĭonsider layer separation carefully. The back layer will be the background and the front layer will be your logo with transparency. Please note that both channel store icons must have 2 layers. In the case of our ContentView example, that means that we don’t actually have to apply the same foregroundColor modifier twice, like we’re doing above (since foreground colors automatically become part of the SwiftUI environment).You will need 2 channel store icons that will be listed in the Apple TV store. Specifying an alignment for a background is done the exact same way, by passing an alignment argument when using the background modifier.Īn overlay or background also inherits all of its parent’s environment values. For views that are fully resizable (like our above LinearGradient), the alignment doesn’t matter (since those views will be resized to fit their parent view anyway), but for smaller views, specifying an alignment lets us move a view to any of its parent’s corners.įor example, here’s how we could add a star image overlay to the top-trailing corner of our ContentView: SwiftUI also supports adding overlays to views as well, which essentially act as the inverse of backgrounds - in that they’re rendered on top of their parent views (with the same sizing behaviors as we explored above).īoth overlays and backgrounds also support alignment customization, which lets us decide how such a view should be placed within its parent’s coordinate system. That way, the size of a given background will always perfectly match the size of its parent view. Of course, the simplest way to avoid drawing a background outside of the bounds of its parent view is to simply let the SwiftUI layout system automatically determine the size of each background. Here’s how we could use that modifier to instead apply our LinearGradient background directly to our Text-based view, which makes that background take on the exact same size as our text itself (including its padding): However, sometimes we might not want a given background to stretch out to fill all available space, and while we could address that by applying various sizing modifiers to our background view, SwiftUI ships with a built-in tool that automatically resizes a given view’s background to perfectly fit its parent - the background modifier. The reason that the above ContentView is rendered across all of the available screen space is because a LinearGradient will always occupy as much space as possible by default, and since a any stack’s size defaults to the total size of its children, that leads to our ZStack being resized to occupy that same full-screen space.
