Iterating Through a Dictionary in Swift

Question

I am a little confused on the answer that Xcode is giving me to this experiment in the Swift Programming Language Guide:

// Use a for-in to iterate through a         


        

Answer 1

You can also use values.makeIterator() to iterate over dict values, like this:

for sb in sbItems.values.makeIterator(){
  // do something with your sb item..
  print(sb)
}

You can also do the iteration like this, in a more swifty style:

sbItems.values.makeIterator().forEach{
  // $0 is your dict value..
  print($0) 
}

sbItems is dict of type [String : NSManagedObject]
