This code is tested and works. It will warn you if the file already exists. The save panel and the file replacement alert will be appear in whatever language Mac OS X is set to use (see screenshot for Japanese example):

- (IBAction)saveTestFile:(id)sender 
{
    NSString *saveString = [NSString stringWithFormat:@"Hello World, it's %@!", [NSDate date]];
    NSSavePanel *savePanel = [NSSavePanel savePanel];
    if ([savePanel runModal] == NSFileHandlingPanelOKButton)
    {
        NSURL *saveURL = [savePanel URL];
        NSError *error = nil;
        if (![saveString writeToURL:saveURL atomically:YES encoding:NSASCIIStringEncoding error:&error])
        {
            NSLog(@"Unable to save file: %@", error);
        }
    }
}
