Summary:
Local functions cannot be made recursive.

Steps to Reproduce:
func a() {
    func f(a: Bool) {
          if a {
              f(false)
          }
      }
}

Expected Results:
Code compiles.

Actual Results:
Error: “Local functions cannot reference themselves”.

Regression:
Member or global functions can be recursive.

Notes:
My temporary work around is to define f as an implicitly unwrapped optional:

var f: (() -> ())!
f = {
    ….
   f()
    ….
}
