Exercise - Type Properties and Methods Imagine you have an app that requires the user to log in. You may have a User struct similar to that shown below. However, in addition to keeping track of specific user information, you might want to have a way of knowing who the current logged in user is. Create a currentUser type property on the User struct below and assign it to a user object representing you. Now you can access the current user through the User struct. Print out the properties of currentUser. struct User { var userName: String var email: String 10 var age: Int 11 12 13 There are other properties and actions associated with a User struct that might be good candidates for a type property or method. One might be a method for logging in. Go back and create a type method called logIn(user:) where user is of type User. In the body of the method, assign the passed in user to the currentUser property, and print out a statement using the user's userName saying that the user has logged in. Below, call the logIn(user:) method and pass in a different User instance than what you assigned to currentUser above. Observe the printout in the console. 19 20
