In a dictionary you have a key and a value, in order for you to access the value of a dictionary you have to use it's key.
**let dictionary = ["Key":"Value"]
So for example :
// Let's create a dictionary of cars
let cars = ["Key 1":"Ford Fiesta","Key 2":"BMW X5", "Key 3":"Audi S4"]
// Now let's access a car by using it's corresponding key.
cars["Key 1"]
// With this key, I am getting "Ford Fiesta".
/*
Ok so now let's say that you want to go riding a car.
This is capturing the value of "Key 2" and assigning it to a constant named bmw.
*/
let bmw = cars["Key 2"]
// Now you can use this constant in other places, for example.
println("Harley likes to ride his new \(bmw)")
This will print Harley likes to ride his new BMW X5.
Hope this explanation helps you understand a bit better and solve your challenge.
Good luck
