removeObjectsAtIndexes for Swift arrays

Question

What is a Swift array equivalent to NSMutableArray\'s -removeObjectsAtIndexes:? Removing each index one by one doesn\'t work, as remaining indexes

Answer 1

Here is the solution I currently use:

extension Array {
    mutating func removeObjectAtIndexes(indexes: [Int]) {
        var indexSet = NSMutableIndexSet()

        for index in indexes {
            indexSet.addIndex(index)
        }

        indexSet.enumerateIndexesWithOptions(.Reverse) {
            self.removeAtIndex($0.0)
            return
        }
    }

    mutating func removeObjectAtIndexes(indexes: Int...) {
        removeObjectAtIndexes(indexes)
    }
}
