Least complicated answer 1st: There's no distinction between your next two examples. By default, house accessors are atomic.
What exactly prevents One more Main from accessing the memory address? The cache coherency protocol currently manages entry rights for cache traces. So if a core has (temporal) special obtain rights to the cache line, no other Main can obtain that cache line.
(Be aware: @synthesize is now the default conduct in latest variations of LLVM. There is certainly also no really need to declare instance variables; they will be synthesized routinely, too, and could have an _ prepended for their identify to avoid accidental immediate obtain).
