SwiftUI GeometryWriter

The GeometryWriter writes the minimum frame to a View.

It is the opposite of a GeometryReader, as in that the GeometryReader will take up as much space as possible and the GeometryWriter will take up as little space as possible, constraining a view to it’s visible frame. Any area with opacity 0.0 will be cropped.

The blue border is the resulting frame of a view in a GeometryWriter.

Code Example

import SwiftUI
import GeometryWriter

struct ContentView: View {
    @State private var active: Bool = false
    var body: some View {
        GeometryWriter { _ in
            Toggle(isOn: $active) {
