Swift uses Automatic Reference Counting (ARC) to manage memory. ARC tracks and frees memory automatically, without requiring programmers to write code for this. In contrast, languages like C++ require manual memory management, and Java’s garbage collection runs at certain times, sometimes causing slowdowns. Swift’s ARC is better at keeping memory under control, even inside functions and closures. With ARC, Swift sits between fully automated and manual memory handling. ARC helps make Swift apps both fast and easier to build, because you do not need to worry as much about memory bugs.
