Swift Filter Array By Index Range

Question

I have an array, say with 100 items in it, and I want to filter out all the items between 20-30.

Something like this, but this isn't correct obviously:

myArray.filter_by_indices(20...30)

I searched and searched, and couldn't find an answer.

You don't need a filter. You can simply call removeSubrange.

myArray.removeSubrange(20..30)

And for the sake of completeness, here is an option using a filter:

myArray = myArray.enumerated().filter { $0.offset < 20 || $0.offset > 30 }.map { $0.element }
