prepare-ChangeLog does not include Swift functions which contain local vars Once the parser matches a variable or function it loses reference to any current function it was tracking. So when a function defines a local var, the var is matched and the containing function is lost. For example: 1 class SomeClass { 2 func aClassMethod() { 3 var local: Local 4 } 5 } Changes to aClassMethod will never cause (SomeClass.aClassMethod) in the ChangeLog because the range of [3, 3, local] is recorded instead.
