There are actually a lot of different variants of how these things do the job dependant upon whether or not the Qualities are scalar values or objects, And exactly how retain, copy, readonly, nonatomic, and many others interact. Generally the residence synthesizers just know how to do the "appropriate thing" for all combinations.
The principle of Atomicity is frequent among atomic transactions and atomic operations, but they usually are linked to unique domains.
/unpack/DEBIAN/Regulate file. It is possible to run a lot less ./unpack/DEBIAN/Management or use almost every other strategy you prefer.
An atom is neither a solid object nor the smallest device known to scientists. As a substitute, an atom is manufactured from a number of particles that interact according to particular regulations. At its core, an atom is actually a nucleus surrounded by a cloud of electrons.

The final two are equivalent; "atomic" could be the default actions (Take note that it is not truly a key phrase; it is specified only via the absence of nonatomic -- atomic was extra being a key phrase in current variations of llvm/clang).
Assuming that you'll be @synthesizing the tactic implementations, atomic vs. non-atomic variations the created code. When you are crafting your own private setter/getters, atomic/nonatomic/keep/assign/copy are basically advisory.
The only most important characteristic of the atom is its atomic quantity (commonly denoted from the letter Z
