2,898 PointsHello am currently losing me mind on this challenge (array inside nested dictionary).
I would like to solve it on my own, but I need some advices. Could you explain to me how to access or call a String which is inside an array that it self is inside a nested dictionary? (e.g. - movieDictionary = [String: [String: [String]]] - )
Any other advices are appreciated!
cheers,
Ken
let movieDictionary = ["Spectre": ["cast": ["Daniel Craig", "Christoph Waltz", "LÊa Seydoux", "Ralph Fiennes", "Monica Bellucci", "Naomie Harris"]]]
var leadActor: String = ""
// Enter code below

you need to access each array/dictionary at a time, starting from the outside and going in. (Really hope this will make sense :) )
Imagine that you are building an app where people can store all their clothes. Each person has their own row, which contains a number of dictionaries - one for each type of clothes. The types of clothes are sorted by colour (just to have the same type of structure as you have...).
var clothesDictionary = [
"person1": ["shirts": ["blue", "black"], "pants": ["black", "white"]],
"person2": ["shirts": ["pink", "red"], "pants": ["cowboy", "black"]]
]
/* Access the colour of the second pair of pants for person2...
- Since I don't know if I have a person2, I have to check if he exists first.
- Then check if he has any pants, and then I can get out the colors.*/
if let person = clothesDictionary["person2"], let pants = person["pants"] {
var secondPantsColor: String = pants[1]
}
Hope that it can help you :)
