Please help me solve this in Swift programming using Xcode

App Exercise - Mile Times and Congratulations Note These exercises reinforce Swift concepts in the context of a fitness tracking app The Runningworkout struct below holds information about your users' running workouts. However, you decide to add information about average mile time. Add a computed property called averageMileTime that uses distance and time to compute the user's average mile time. Assume that distance is in meters and 1600 meters is a mile. Create an instance of Runningworkout and print the averageMileTime property. Check that it works properly. struct Runningworkout var distance: Double var time: Double var elevation: Double In other app exercises, you've provided encouraging messages to the user based on how many steps theyve completed. A great place to check whether or not you should display something to the user is in a property observer. In the Steps struct below, add a willSet to the steps property that will check if the new value is equal to goal, and if it is, prints a congratulatory message. Create an instance of Steps where steps is 9999 and goal is 10000, then call takeStep() and see if your message is printed to the console struct Steps var steps: Int var goal:Int mutating func takeStep) steps + 1
