![]() ![]() The downside is it only works if your app is only portrait since it doesn't adapt to the different orientations. ![]() So, what if you want an element to consume like 1/4th or 1/3rd of the screen? Well, you can go. You can use this information to size/position our view relative to the size/position of it's superview and any view in the hierarchy.īefore you indulging deeper into geometry reader, let's look at an alternative way to fetch frame properties of a view without using geometry readers. GeometryReader is an special container view like any other container view such as VStack, ZStack and Group but the special part is, the closure this container has, have an parameter of type GeometryProxy with contains information about this containers size and safeAreaInsets, also it has an function frame(in: CoordinateSpace) -> CGRect which give us frames for an certain CoordinateSpace (more on this in later section of the article). There are also conditions where you need to define the size or position of a view relative to it's parent, and for this particular use case, SwiftUI have provided us with GeometryReader. Aligning views across stacks Create a custom alignment and use it to align views across multiple stacks. ![]() This layout system provides us a lot of simple and flexible ways to define our view's position, but sometimes scenarios arise where you need to have specific frames or size set for a view either by setting some concrete value for which SwiftUI have provided. Position views inside a stack using alignment guides. SwiftUI Layout works very differently than UIKit Wherein UIKit we dealt with raw frames, and either added constraints accordingly or have some concrete frame-set to specify the position of views, in SwiftUI, the layouts are defined in form of stacks, spacers and paddings. ![]()
