Write a Playground file in SWIFT to create a dictionary for at least 5 products, in which each key is a product name (e.g., “Stawberry Icecream”) and each value is a tuple including the category and price of the corresponding product (e.g., (“Dissert”, 3.99))
Declare three functions:

• lowestPrice function returns name and price of the product that has the lowest price among all given products.

• highestPrice function returns name and price of the product that has the highest price among all given products.

• price function takes a product dictionary and a reference to a function as arguments. It returns the information (i.e., product name and price) of the product that has either the lowest price or the highest price.

  call function price and pass a reference to lowestPrice function, and make sure you get the correct returned value.
  call function price and pass a reference to highestPrice function, and make sure you get the correct returned value.
