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

This is a user-defined function to iterate through a dictionary:

func findDic(dict: [String: String]){
    for (key, value) in dict{
    print("\(key) : \(value)")
  }
}

findDic(dict: ["Animal":"Lion", "Bird":"Sparrow"])
//prints Animal : Lion 
         Bird : Sparrow
