Hello Yupin,

I hope I can help you with your problem. When you create a dictionary, you assign a value to every key you have inside your dictionary. You can add as many keys inside your dictionary as you want. So, for example, let's create a dictionary called musicDictionary.

var musicDictionary = ["title": "Legend", "artist": "Drake", "album": "If You're Reading This It's Too Late"]

I hope I could help you understand the syntax. Feel free to ask if you got any further questions.
