![]() ![]() However, the designer wants us to align the horizontal rule with text with a red border. Inside each VStack, there are two Text elements - One with a red border and the other with blue.īetween these two VStacks, there is a horizontal rule. Inside it, there are two VStack children (With a yellow border) one on each side. If you look at the view from the very top, there is an enclosing parent HStack view with a black border. Let's start with an example to see how it works in action. Similarly, I can customize the layout in such a way that, I can also match the leading edge of one view with the trailing edge of another and vice versa.įortunately, SwiftUI offers an easy solution for these kinds of use-cases through a custom alignment feature. That way they don't have to know about each other, but as long as there is a fixed third reference (In this case, a red line), their positions relative to each other will match. In SwiftUI, I can't align the horizontal centers of these two views directly, but with custom alignment, I can specify the fixed center and ask both of them to align their horizontal centers. For example, consider the fixed line like this and two views around it. They allow developers to specify a fixed line and then lay out views relative to that line. Things become complicated when they are part of the same view hierarchy, but have different immediate parents.Ĭustom alignments in SwiftUI offer elegant and reliable solutions in such cases. This works for most cases but also fails when you want to lay out views by stating explicit conditions such as aligning the centers of these two views or aligning the baseline of one view with the top of another view. ![]() ![]() Unlike an explicit constraint system where you clearly specify how you want to layout views with respect to each other's leading, trailing, or center edges, SwiftUI offers a more subtle way to arrange views instead of going into too many details. SwiftUI offers a novel way to lay out views in iOS apps. ![]()
