+#  SwiftUI Layout Inspector
+
+Ole Begemann, 2022-09
+
+Based on: [objc.io, Swift Talk episode 318, Inspecting SwiftUI's Layout Process (2022-08)](https://talk.objc.io/episodes/S01E318-inspecting-swiftui-s-layout-process)
+
+Inspect the layout algorithm of SwiftUI views, i.e. what sizes views propose to
+their children and what sizes they return to their parents.
+
+![Layout Inspector screenshot on iPhone simulator](assets/LayoutInspector-screenshot.png)
+
+## Requirements
+
+iOS 16.0 or macOS 13.0 (requires the `Layout` protocol).
+
+## Instructions
+
+1.  Edit the `subject: some View` property in `ContentView`. It should contain
+    the view tree you want to inspect.
+    
+2.  Add `.debugLayout()` at each point in the view tree where you want to inspect
+    the layout algorithm (what sizes are being proposed and returned). 
+        
+    Example of a `subject` property with a few inspection points:
+   
+    ```swift
+    var subject: some View {
+        Text("Hello world")
+            .debugLayout("Text")
+            .padding(10)
+            .debugLayout("padding")
+            .background {
+                Color.yellow
+                    .debugLayout("yellow")
+            }
+            .debugLayout("background")
+    }
+    ```
+
+4.  Build and run the app.
+
+    - The subject view is displayed on top.
+    - The table on the bottom displays the sizes that are being proposed at each
+      inspection point in the subject view ("Proposal", and the resulting view 
+      sizes ("Response").
+    - You can tap/click items in the grid to highlight the respective view.
+    - You can use the sliders to modify the size proposed to the subject view.
+    - Some views cache certain layout information. Press "Reset layout cache"
+      after modifying the sliders to reset the caches.
