Adding items to dictionary by key

I have different keys and items to add to a dictionary:

City + Berlin
City + London
City + New York City
Movie + Horror
Movie + Science-Fiction
Movie + Thriller
Food + Burger
Food + Vegetables
Food + Ice Cream
Sports + Baseball
Sports + Soccer
Sports + Tennis
Technology + Apple

I want the matching keys to be one key and the values as an array matching that one key like this:

City: [Berlin, London, New York]
Movie: [Horror, Science-Fiction, Thriller]
etc.

Every pair (one key + matching values) should be together in one UICollectionViewCell.

I have searched for creating and accessing a dictionary, but I just cannot find the right solution for this.

Thank you!

Assuming each of the items you show are strings, you need to declare a dictionary of type [String: [String]] (key is type String and value is an array of String)

let dictionary = [
    "City": ["Berlin", "London", "New York"],
    "Movie": ["Horror", "Science-Fiction", "Thriller"],
    // ...etc.
]
