Trouble with Dictionaries

Hello,

I am trying to insert the String to String tag on my dictionary, but I am getting an error message.

This is the code I have:

let airportCodes: [String: String] = [ "LGA: La Guardia", "LHR: Heathrow", "CDG: Charles de Gualle", "HKG: Hong Kong International", "DXB: Dubai Internation"]

There are no errors until I put in "[String: String]" The error message reads: "Contextual type '[String: String]' cannot be used with array literal."

I'm trying to follow the on screen instructions as closely as possible, so any help is appreciated. Thanks!

Hi,

As Strings will be in double quotes, we need to have the key string and value string in double quotes individually, instead of clubbing them. Below is the syntax: let airportCodes: [String: String] = [ "LGA": "La Guardia", "LHR": "Heathrow", "CDG": "Charles de Gualle", "HKG": "Hong Kong International", "DXB": "Dubai Internation"]
