int main(int argc, const char * argv[]) {
    @autoreleasepool {
        @try {
            return 0;
        }

}

Or, to be a bit more clear about the kinds of things that could happen depending on runtime values:

#import <Foundation/Foundation.h>

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        @try {
            BOOL yn = YES;
            if (yn) {
                NSLog(@"Early return.");
                return 0;
            }
            NSLog(@"Never reached.");
        }
        @finally {
            NSLog(@"OHAI");
        }
    }
    return 0;
}
