Code that makes my life in SwiftUI easier:

  • read and assign geometry preferences (https://finestructure.co/blog/2020/1/20/swiftui-equal-widths-view-constraints)

    Usage:

    import SwiftUI
import SwiftUITools

struct ContentView: View {
    enum LeftColumnWidth: Preference {}
    let leftColumnWidth = GeometryPreferenceReader(
        key: AppendValue<LeftColumnWidth>.self,
        value: { [$0.size.width] }
    )
    
    @State private var minWidth: CGFloat? = nil

    var body: some View {
        VStack {
            HStack {
                Text("a very long")
                    .read(leftColumnWidth)
                    .frame(minWidth: minWidth)
                Text("text")
            }
            HStack {
                Text("short")
                    .read(leftColumnWidth)
                    .frame(minWidth: minWidth)
              Text("text")
            }
        }
        .assignMaxPreference(for: leftColumnWidth.key, to: $minWidth)
    }
}

    This will give you:
