Array or Set using keypairs

Forums > 100 Days of Swift

Working through Arrays and Sets I find that when creating an array that uses a keypair i.e. var questions = [String:String] neither append or insert are available. How do you append or update an Array with keypairs?

Thanks in advance.

That's not an array, it's a Dictionary. See this cheatsheet for helpful tips.

Basically, though, you add to a Dictionary using subscript syntax:

var dict: [String: String] = [:]
dict["Charlotte"] = "Grote"
dict["Shauna"] = "Wickle"
print(dict)
//["Charlotte": "Grote", "Shauna": "Wickle"]

Thank you. The cheatsheet is very helpful.
