Mac sandbox created but no NSUserDefaults plist

Question

I\'m trying to track down some issues arising from sandbox creation. Under multiple circumstances it appears that an NSUserDefaults .plist file is not created in Data/Libra

After spending a ton of time found freaking simple solution:

- (void)fixDefaultsIfNeeded{
    NSArray *domains = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory,NSUserDomainMask,YES);
    //File should be in library
    NSString *libraryPath = [domains firstObject];
    if (libraryPath) {
        NSString *preferensesPath = [libraryPath stringByAppendingPathComponent:@"Preferences"];

        //Defaults file name similar to bundle identifier
        NSString *bundleIdentifier = [[NSBundle mainBundle] bundleIdentifier];

        //Add correct extension
        NSString *defaultsName = [bundleIdentifier stringByAppendingString:@".plist"];

        NSString *defaultsPath = [preferensesPath stringByAppendingPathComponent:defaultsName];

        NSFileManager *manager = [NSFileManager defaultManager];

        if (![manager fileExistsAtPath:defaultsPath]) {
            //Create to fix issues
            [manager createFileAtPath:defaultsPath contents:nil attributes:nil];

            //And restart defaults at the end
            [NSUserDefaults resetStandardUserDefaults];
            [[NSUserDefaults standardUserDefaults] synchronize];
        }
    }
}
