  • Automatic Reference Counting (ARC) is a memory management technique used in various programming languages.

Examples

  • In Swift, ARC automatically identifies and frees up memory used by objects that are no longer needed.

  • Using ARC simplifies memory management for developers by reducing manual reference counting.

  • This is one of the reasons ARC has become what it has.

  • You cannot leave your ARC without a respirator.

  • It looks like game streaming on ARC is basically broken now.

  • As acknowledged in the 2013 CAFR, had the ARC been made, it would have resulted in a general fund deficit.

Etymology

ARC is an abbreviation of Automatic Reference Counting, which you can picture as an automatic counter that keeps track of how many 'references' point to an object in memory. So, ARC literally means a memory method that 'automatically counts' references and 'frees' an object when the count reaches zero.
