Swift 3.0 array "contains" argument compiler error

Here is the statement that's causing trouble. This worked perfectly in Swift 2.2 but is not working in 3.0 and Xcode 8.

  keys = keys
        .enumerated()
        .filter { !indexesToRemove.contains($0.index) }        
        .map { $0.element }

Right at $0.index xCode is throwing a compiler error:

Value of tuple type '(offset: Int, element: Any)' has no member 'index'

As far as I know $0 represents objects in the keys array. What tuple is it talking about?

index has been changed to offset in Swift 3 (don't ask me why):

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