When creating a game with Unity, we often reach the point where we need to save data that we need at a later point in time. This could be something simple, like a table of high scores, or a lot more complex, like the state of the game that got paused and now needs to be resumed exactly the way the user left it when they quit it earlier. Maybe you have tried this before using PlayerPrefs but your data was too complex to save it in there. Or you have tried SQL only to find it to be very complicated and cumbersome to use.
Realm can help you achieve this easily and quickly with just some minor adjustments to your code.
