Swift: function with default parameter before non-default parameter

Question

say I have a function that has non-default parameter after default parameter like this:

func f(first:Int = 100, second:Int){}

how can I call it

Answer 1

If it is a method on a class, you need to call it like this

class Test
{
    func f(first:Int = 100, second:Int)
    {
        println("first is \(first)")
        println("second is \(second)")
    }

    func other()
    {
        f(second: 4)
        f(first: 30, second: 5)
        //f(4) will not compile, and neither will f(9,12)
    }
}

If the function f is global, you need to call it like this:

f(4)
f(first: 30, 5)

This prints:

first is 100
second is 4
first is 30
second is 5
