"Memory is automatically controlled" - how?

I know that the biggest difference between GC and ARC is that GC is a run-time process, while ARC works at compile time. Therefore, when working with ARC, the developer must take care of memory in some scenarios.

However, according to this , there is no space left for SWFT to interact with the developer .

So how do they do it? Do they have runtime to clear memory or something else?

Swift uses ARC just like Objective-C does. ARC is discussed in detail .

In short:

  • There is no garbage collector.
  • Objects live as long as (strong) links exist.
  • Strong links cannot be cyclic, otherwise you will be a memory leak. Use weak references for interrupt loops.
