How can I remove all nil elements in a Swift array?

Question

Basic way doesn\'t work.

for index in 0 ..< list.count {
    if list[index] == nil {
        list.removeAtIndex(index) //this will cause array index out o         


        

Answer 1

Now in swift 4.2 you can use

list.compactMap{ $0 }

• list.flatMap { $0 } is already deprecated.
