Question

NSURL *URL = [NSURL URLWithString:@"https://accounts.google.com/SignUp"];
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 90000
if (URL) {

    if ([SFSafariViewController class] != nil) {
        SFSafariViewController *sfvc = [[SFSafariViewController alloc] initWithURL:URL];
        sfvc.delegate = self;
        [self presentViewController:sfvc animated:YES completion:nil];
    } else {
        if (![[UIApplication sharedApplication] openURL:URL]) {
            NSLog(@"%@%@",@"Failed to open url:",[URL description]);
        }
    }
}
#else
 [[UIApplication sharedApplication] openURL:URL];
#endif

See here for a discussion on __IPHONE_OS_VERSION_MAX_ALLOWED

Basically, as you mentioned, this is a question for Xcode, which is answered by it at compile time, not for your device. You should be instead doing a check one of the ways implemented here.
