Design a simple daily meds/supplements checklist screen for an iOS app. Users should be able to add items to the list, tick a checkbox to mark today’s dose, and remove items they no longer need. All checkmarks should clear automatically at the start of a new day so the list is reset for today. Keep everything on-device; implement the list with a UITableView and store the items plus today’s completion state using UserDefaults. Use Objective-C.
