Type 'AnyObject' does not conform to protocol 'SequenceType'
what does this menas?
who can help me ,thks a lot!!!!
Apple states in The Swift Programming Language:
The for-in loop performs a set of statements for each item in a range, sequence, collection, or progression.
Right now, directoryContent
is just conforming to protocol AnyObject
, so you can't use for loops over it. If you want to do so, you have to do something similar to the following:
for item in directoryContent as [AnyObject] { //Do stuff }
