Whenever you deliver an object a launch information, its keep rely is decremented by 1. Once you deliver an object an autorelease information, its keep rely is decremented by 1 at some stage in the future. If an itemʼs keep count is reduced to 0, it can be deallocated.
"[But] such a touching does probably not Atomic Wallet seem sensible on the atomic scale simply because atoms do not need nicely-described outer surfaces."
