How do I delete / remove a city from the Weather app in iOS 7?
Deleting a city from the Weather app in iOS 7 is a little different than in previous versions, where you edited a list of locations. When you are in the app, if you aren't already in list view, go to it by tapping the list icon in the bottom right of the screen. Go to the city you want to delete and simply swipe right to left on it. This reveals the delete button. You can also change the order of the list by tapping and holding a city then dragging it to a new position.
