The main difference between Manual Reference Counting (MRC) and Automatic Reference Counting (ARC) in Apple iOS is how they manage memory. MRC is the traditional method where developers manually manage memory using retain, release, and autorelease methods. ARC, introduced in Xcode 4.2, automatically manages memory by adding and removing retain and release messages for objects as they are created, assigned, and released.nnMRC provides more control over the memory management process but requires more effort from developers, while ARC simplifies the process and reduces the chance of memory leaks.
