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).40 Funny Doodles For Cat Lovers and Your Cat Crazy Lady FriendĦ0 Quotes On Cheating Boyfriend And Lying Husbandġ20 Free Airport WiFi Passwords From Around The WorldĤ Ways To Boost And Optimize Wireless WiFi Signal Strength And SpeedĦ Virtual SIM Phone Number App For iOS And Android SmartphonesĦ Best VPN for Gaming – No Lags, 0% Packet Loss and Reduce Ping msħ Free Apps To Find, Spy And Track Stolen Android Smartphoneġ0 Best Free WordPress Hosting With Own Domain And Secure Securityġ0 GPS Tracker For Smartphones In Locating Missing, Abducted And Kidnapped Childħ Laptop Theft Recovering Software with GPS Location Tracking and Sp圜amĭownload Free McAfee AntiVirus Plus for 30 Daysĭownload the New Norton Antivirus, Internet Security 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.
