Summary:
func fibonacci(n: Int) -> Int {
    func fibonacciStep(a: Int, b: Int, count: Int) -> Int {
        if (count > 0) {
            return fibonacciStep(b, a+b, count-1)
        } else {
            return a
        }
    }
    return fibonacciStep(0, 1, n)
}

results in 

Playground execution failed: error: Execution was interrupted, reason: EXC_BAD_ACCESS (code=1, address=0x1).
The process has been left at the point where it was interrupted, use "thread return -x" to return to the state before expression evaluation.
