You’re trying to iterate an array of something and put each element into a
tuple of ( index, element ), that’s not going to work.
Either
for element in downlaodFileArrayController.arrangedObects {}
or
for (index, element ) in
downloadingFilesArrayControler.arrangedObjects.enumerate() {}
If you’re on Swift 1.2 I think it’s enumerate(
downloadingFilesArrayController.arrangedObjects ) instead of the enumerate on
the end.
Can’t say the error message makes any sense to me however, not that the one I
get in Xcode 7 makes much more sense.
