callingCodeForCountryCode returning NULL

[hydralisk01]

• Running this function on country codes from [NSLocale ISOCountryCodes]
• I suspect the Default.phoneformat file could be missing something? I am getting the file from /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AppSupport.framework/

    RMPhoneFormat *format = [RMPhoneFormat instance];

    NSMutableArray *invalidCodes = [[NSMutableArray alloc] init];

    for (NSString *countryCode in [NSLocale ISOCountryCodes])
    {
        NSString *callingCode = [format callingCodeForCountryCode:countryCode];
        if (!callingCode) [invalidCodes addObject:countryCode];
    }

    NSLog(@"invalidCodes: %@", invalidCodes);
