Map a void (non-returning function) over an array

Question

Title is self-explanatory, is there any way of mapping, for example, addGestureRecognizer over an array of UIGestureRecognizers. I\'ve been fiddlin

Answer 1

map is designed to return an array from another array that has had a given transformation applied to it (by transforming each element). Therefore naturally the function that you pass to it has to return the transformed element.

In your case, you're not actually transforming the elements, you just want to use them in an argument of a function. To do this, you can use forEach.

recognizers.forEach(MyWebOutlet.addGestureRecognizer)
