• ARC is a compile-time feature that automatically inserts retain and release calls based on static code analysis, eliminating the need for manual memory management. GC is a run-time process that periodically collects and frees unused objects[1].

• ARC has no runtime overhead, while GC requires a separate process to manage memory, which can introduce latency[1].

• ARC is supported on Apple platforms starting from Xcode 4.2 (2011). GC was supported in Mac OS X v10.5 but has been deprecated in favor of ARC in more recent versions of macOS and iOS[1].
