But

Answer 1

Swift 3: Use swift closure to perform the same operation.

If your array is like

var numbers = [0, 1, 2, 3, 4, 5]

and indexes you want to remove

let indexesToBeRemoved: Set = [2, 4]

numbers = numbers
    .enumerated()
    .filter { !indexesToRemove.contains($0.offset) }
    .map { $0.element }
and result

print(numbers) // [0, 1, 3, 5]

Swift 3: Here is same operation with JSON Object (dictionary)

var arrayString = [
    [ "char" : "Z" ],
    [ "char" : "Y" ],
    [ "char" : "X" ],
    [ "char" : "W" ],
    [ "char" : "V" ],
    [ "char" : "U" ],
    [ "char" : "T" ],
    [ "char" : "S" ]
]

let arrayIndex = [2, 3, 5]

arrayString = arrayString.enumerated()
    .filter { !arrayIndex.contains($0.0 + 1) }
    .map { $0.1 }

print(arrayString)

[["char": "Z"], ["char": "W"], ["char": "U"], ["name": "T"], ["name": "S"]]
