Hello. I am working on a game which is to run on ios. It is nearing completion, but I am having a small issue. I wrote some code to save and load values including highscores, coins, and items purchased using .txt and .ini files. I tested them on windows and on android virtual devices, and it worked as expected. However, when I tested on an ios device, my data never saves, and resets back to default values each time. This happens every time I close the app by swiping up on it, and whenever I reupload it to the phone. Any ideas on how to fix this ios issue?
