title: Value of label resets after the app is force quit in Swift and Xcode
body: <p>I am new to Xcode and Swift programming. I am making an app that tracks water drank in a day. For some reason though, the fluid ounces (label) reset when I force quit the app (tapping red circle with minus, or swiping away app card). Is there any way I can keep the value of the label from resetting when the app is force quit?</p>
