Assuming you are @synthesizing the strategy implementations, atomic vs. non-atomic variations the generated code. In case you are writing your very own setter/getters, atomic/nonatomic/keep/assign/duplicate are just advisory.

I did read through a little something about an Exclusive lock check, so I have a achievable principle that if the thread resumes and executes the STREX, the os monitor leads to this call to fail which can be detected as well as the loop might be re-executed utilizing the new price in the procedure (department back again to LDREX), Am i appropriate right here ?

What "atomic" does not do is make any assures about thread security. If thread A is asking the getter at the same time with thread B and C contacting the setter with various values, thread A may well Atomic get any one of the three values returned -- the a single previous to any setters being referred to as or either on the values handed into your setters in B and C.
