So, if we have this feature for free and everything happens magically, should you care about it? Yes, you should, because it doesn’t mean you can’t make mistakes. Both Kotlin and Swift have this process automated, unlike C, C++. It means that the programmer is not responsible for the deletion The benefits are clear without a shadow of doubt. That’s why the system removes unreachable objects. You don’t have unlimited memory and you have to reclaim it. When the user closes the task details screen, all objects related to it should be removed. For this action, your app dynamically allocates additional memory to the heap. When the user clicks on an item on the list, the details screen is presented. First, your app allocates memory for displaying the task list on launch. There is a task list screen and a task details screen. 3) The dark blue rectangles indicate objects eligible for garbage collection, which are then removed from the memory heapĪn object becomes a good candidate for garbage collection when there are no references to it. 2) Memory heap with allocated memory blocks (blue rectangles)Īfter a while, some objects become eligible for garbage collection, and are then removed from the memory heap. When your app starts, it allocates memory to objects (reference types) in runtime. This is your memory heap (don’t confuse it with stack) assigned to your app. Still don’t get it? Ok, so let me explain this using some pictures and a simplified example. The Garbage Collection process, also known as automatic memory management, is the automatic recycling of dynamically allocated memory, as explained here. I left you alone with this problem, but now I want to make it up to you by describing this difference. In my previous article, which you can find here, I mentioned
