Hi, I am working on project 1 and I am stuck when creating an array of dictionaries to hold all of my player information. My thought process is as follows:
1) Create an array to hold all player names. Create a seperate dictionary to hold player height, player experience, and player guardian information. 2) Create an array to hold the player height, player experience, and player guardian dictionaries.
I am stuck when typing the following line of code:
let playerInformation = [playerName, playerHeight, playerExperience, playerGuardian]
I receive a "Type of expression is ambiguous without more context"
I'm assuming I have to tell the array what types my dictionaries are, but I can't seem to figure this part out.
NOTE: I also tried creating a single dictionary to hold the player info as follows:
let playerOne: [String: AnyObject] = ["name": "Arnold Willis", "height": "43", "hasExperience": "false", "guardianName": "Claire Willis"]
This resulted in a "value of type string does not conform to any object" error.

let playerOne: [String: String] = ["name": "Arnold Willis", "height": "43", "hasExperience": "false", "guardianName": "Claire Willis"]
and then when you have multiple players
let playerInformation: [[String: String]] = [playerOne, playerTwo, playerThree]
