Proportional height (or width) in SwiftUI
You can make use of GeometryReader. Wrap the reader around all other views and use its closure value metrics to calculate the heights:
let propHeight = metrics.size.height * 0.43Use it as follows:
import SwiftUIstruct ContentView: View { var body: some View { GeometryReader { metrics in VStack(spacing: 0) { Color.red.frame(height: metrics.size.height * 0.43) Color.green.frame(height: metrics.size.height * 0.37) Color.yellow } } }}import PlaygroundSupportPlaygroundPage.current.liveView = UIHostingController(rootView: ContentView())
