Functions that recursively reference themselves in Swift

Recursive functions currently cause compile-time error in xcode projects using swift, but work just fine in a playground. In the release notes of Xcode 6 beta 4 :

Nested functions that recursively reference themselves or other functions nested in the same outer function crash the compiler. (11266246) For example:

func foo() {
  func bar() { bar() }
  func zim() { zang() }
  func zang() { zim() }
}

Workaround: Move recursive functions to the outer type or module context

What is meant by Move recursive functions to the outer type or module context?

It means that you should declare the function outside of the other function:

func bar() { bar() }
func zim() { zang() }
func zang() { zim() }
func foo() {
}
