64-bit Objective-C

On 64-bit you can use properties to generate both accessor methods and the instance variable itself. This code compiles and works on Snow Leopard:

#import <Foundation/Foundation.h>

@interface Test : NSObject
@property (retain) NSString *name;
@end

@implementation Test
@synthesize name;
@end

int main (int argc, const char * argv[]) {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    Test *test = [[Test alloc] init];
    [test setName: @"TheName"];
    NSLog(@"Name is %@\n", [test name]);
    [pool drain];
    return 0;
}

Here is the console:

Program loaded.
