What's the best way to convert an IndexSet to an int array?

Question

I want to convert NStableView.selectedRowIndexes to an int array. Is there a fast way to do that? Or should I iterate the IndexSet and push each item to an array?

Answer 1

There are two simple ways you can do it.

1) Use map

let indexes = tableView.selectedRowIndexes.map({$0})

2) Pass the NSIndexSet into the Array initialiser

let indexes = Array(tableView.selectedRowIndexes)
