Question regarding private queue concurrency
Raw
CoreDataThreadingQuestion.m
__block NSManagedObject* object = nil;
[privateQueueContext performBlockAndWait:^{
object = [SomeClass methodThatExecutesFetchRequestReturningObjectUsingContext:privateQueueContext];
}];
// Is it safe to use object here?
NSLog(@"object: %@", object);
