Exercise - Memberwise and Custom Initializers If you completed the exercise Structs, Instances, and Default Values, you created a GPS struct with default values for properties latitude and longitu your GPS struct again, but this time do not provide default values. Both properties should be of type Double. truct GPS { Now create a constant instance of GPS called somePlace, and use the memberwise initializer to set latitude to 51.514004, and longitude to 0.125226 values of somePlace's properties.

How do I solve this using Swift code? Question 3 of 10 part 1

Please find attached an image of the previous exercise I did before as a reference. I just don't know how to do it without providing default values.

Exercise - Memberwise and Custom Initializers If you completed the exercise Structs, Instances, and Default Values, you created a GPS struct with default values for properties of latitude and longitude. Create your GPS struct again, but this time do not provide default values. Both properties should be of type Double. 6 struct GP { 7 8 9. } Now create a constant instance of GPS called somePlace, and use the memberwise initializer to set latitude to 51.514004, and longitude to 0.125226. Print the values of somePlace's properties. 11 12 In Structs, Instance, and Default Values, you also created a Book struct with properties title, author, pages, and price. Create this struct again without default values. Give each property the appropriate type. Declare your favoriteBook instance and pass in the values of your favorite book using the memberwise initializer. Print a statement about your favorite book using favoriteBook's properties. 14 15
