Partial libraries used: StravaSwift - I extracted only what I needed from this library to keep the code base light. The main benefits of using this was the intial configuration when authorizing an Athlete.
Going forward I would improve the callbacks in the StravaSwift library so they are more defined for success/failure cases. Add more failure case for no network, or upload failures.
Clone the repository and open the DailyCommute.xcworkspace project. The use case is fairly straight forward. First authorize via the Strava login. From there you should see a detailed list of your past activities. Create a new activity or daily commute by pressing the Track button. You will be prompted to allow location services (I kept them as only when the app is in use for this simple use case), after allowing location services start your commute.
When finished press Stop Commute and save your activity. The view will dismiss and refresh the main list of activities.
