How do I alignment guides in SwiftUI?

To align guides in SwiftUI, you can use the alignmentGuide modifier. This modifier allows you to specify how a view should align itself relative to its parent or other sibling views. Here’s a basic example:

struct ContentView: View {
    var body: some View {
        HStack(alignment: .top) {
            Text("Hello")
                .alignmentGuide(.top) { d in d[.bottom] }
            Text("World")
        }
    }
}

In this example, the alignmentGuide modifier is used to align the bottom of the "Hello" text with the top of the "World" text.

For more advanced layouts and dynamic adjustments, you might want to explore the new features and improvements in SwiftUI presented at WWDC. For example, the session What’s new in SwiftUI covers various enhancements, including scrolling and alignment controls, which could be useful depending on your specific needs.
