Remove multiple indices from array

Question

I have an array and I want to remove a bunch of indices

var arr = [0,1,2,3,4,5,6]
var rmIndices = [1,4,5]

What is the best way to remove in

Answer 1

For Swift 3

    var arr = [0,1,2,3,4,5,6]
    let rmIndices = [1,4,5]
    arr = arr.filter{ !rmIndices.contains($0) }
    print(arr)

if you want to produce output very fastly then you can use

    var arr = [0,1,2,3,4,5,6]
    let rmIndices = [1,4,5]
    arr = Array(Set(arr).subtracting(rmIndices))
    print(array)

But it will change order of your array
