How do I solve this using Swift code? 1 of 10

Exercise - Structs, Instances, and Default Values Imagine you are creating an app that will monitor location. Create a GPS struct with two variable properties, latitude and longitude, both with default values of 0.0. Create a variable instance of GPS called somePlace. It should be initialized without supplying any arguments. Print out the latitude and longitude of somePlace, which should be 0.0 for both. Change somePlace's latitude to 51.514004, and the longitude to 0.125226, then print the updated values. Now imagine you are making a social app for sharing your favorite books. Create a Book struct with four variable properties: title, author, pages, and price. The default values for both title and author should be an empty string. pages should default to 0, and price should default to 0.0. Create a variable instance of Book called favoriteBook without supplying any arguments. Print out the title of favoriteBook. Does it currently reflect the title of your favorite book? Probably not. Change all four properties of favoriteBook to reflect your favorite book. Then, using the properties of favoriteBook, print out facts about the book.
