It looks like it's much lower level than that:
#import <Foundation/Foundation.h>
int main()
{
@autoreleasepool {
NSString *testString = nil;
testString = [NSString stringWithUTF8String:"Hello World"];
NSMutableArray* arr = [NSMutableArray arrayWithObject:testString];
[arr addObject:testString];
int length = [arr count];
printf("The length: %d\n", length);
}
}
The length: 0
