Static function variables in Swift

Question

I\'m trying to figure out how to declare a static variable scoped only locally to a function in Swift.

In C, this might look something like this:

int

I don't think Swift supports static variable without having it attached to a class/struct. Try declaring a private struct with static variable.

func foo() -> Int {
    struct Holder {
        static var timesCalled = 0
    }
    Holder.timesCalled += 1
    return Holder.timesCalled
}

  7> foo()
$R0: Int = 1
  8> foo()
$R1: Int = 2
  9> foo()
$R2: Int = 3
