@@ -372,22 +372,8 @@ The example above demonstrates the following style guidelines:
 
 For conciseness, avoid using `self` since Swift does not require it to access an object's properties or invoke its methods.
 
-Use `self` when required to differentiate between property names and arguments in initializers, and when referencing properties in closure expressions (as required by the compiler):
+Use self only when required by the compiler (in `@escaping` closures, or in initializers to disambiguate properties from arguments). In other words, if it compiles without self then omit it.
 
-```swift
-class BoardLocation {
-  let row: Int, column: Int
-
-  init(row: Int, column: Int) {
-    self.row = row
-    self.column = column
-
-    let closure = {
-      print(self.row)
-    }
-  }
-}
