+    Additionally, within the grouping of SwiftUI properties, it is preferred that the properties are also grouped by their dynamic property type. The group order applied by the formatter is determined by the first time a type appears:
+
+    ```swift
+    // WRONG
+    struct CustomSlider: View {
+
+      @Binding private var value: Value
+      @State private var foo = Foo()

+      @Environment(\.layoutDirection) private var layoutDirection
