![]() Watch it carefully and you’ll see the pattern. This dancing dot circles around all the options for frame alignment as we change the frame size. Here is an animated GIF to drive the point home. Change the alignment you used to a State variable and take a look at your options. Position the image within a custom frame: Image ( 'fall-leaves' ). Apple has defined nine of the most common layouts you might want. SwiftUI Image with text header aligned to top of the screen.You just need to start thinking about frames. It’s a super-simple principle that you can apply to get any layout of your choice to work. Add a second ZStack and a frame to the mix, with an alignment guide on the second frame. ![]() Sure, you can give it a bigger frame, but then your circle will occupy the whole thing again. Actually, it is at the bottom too as well being on the leading and trailing edges. Go back to the picture and look at the red frame. You wanted it at the top, so you check the documentation, add an alignment guide to the frame, and try again. Add a ZStack and a frame.īetter, but you didn’t want it in the center. You see, you asked for a circle, didn’t give it a size, and it took as much space as it could. It’s too big, isn’t it? It’s those layout semantics in play. I have a view within which I add a shape (a circle). Crazy, I know, but that’s just how the default semantics work. Normally, the layout semantics ensure that the layout guides just don’t work (at least for frames, that is). Currently building a chat application and I need new messages to appear at the bottom of the screen. Use the regular VStack when you have a small number of subviews or don’t want the delayed rendering behavior of the lazy version. Ios VStack inside ScrollView bottom alignment in SwiftUI. You can influence these rules with your alignment guides. Unlike Lazy VStack, which only renders the views when your app needs to display them, a VStack renders the views all at once, regardless of whether they are on- or offscreen. Containers that are the parents in the semantics above, containers that will organize their siblings using said rules. To lay out/manage space in SwiftUI, you use containers (ZStack, VStack, and HStack). “What does this have to do with alignment guides?” you may ask.
