Array of dictionaries in Swift

Hi

I'm trying to extend the FunFact app by changing the name to Quotes and adding authors to Quotes.

I'm unsure how to initialize the array with Dictionaries.

For example I'm trying to do the following:

var quotesArray: Dictionary<String, String> = [
    [quote: "Quote", author: "Some Guy"]
]

func randomQuote() -> String {
    return quotesArray[Int(arc4random_uniform(UInt32(quotesArray.count)))]
}

Can anyone help me get past this?

Try something like this... ?

let firstQuote = ["author" : "John Appleseed", "quote" : "Insert something inspirational..."]
let secondQuote = ["author" : "Joe Bloggs", "quote" : "Insert something inspirational..."]

var quotesArray = [firstQuote, secondQuote]

No idea if this will work. It should :)

I figured out the issue. I had the keys not wrapped in quotes.

As for the random function, I did the following which solved it:

func randomQuote() -> Dictionary<String, String> {
    return quotesArray[Int(arc4random_uniform(UInt32(quotesArray.count)))]
}

Final result:

var quotesArray = [
["quote": "Some text here", "author": "Some guy"],
["quote": "Some text here", "author": "Some guy"],
["quote": "Some text here", "author": "Some guy"]
]

Thanks :)
