Convert mantles with nested dictionaries

Question

Convert mantles with nested dictionaries

I thought this question would work for my situation, but my lack of experience with Mantle and iOS in general did not end my train of thought. Basically, I have a big chunk of JSON with nested dictionaries and arrays that I want to convert to Mantle objects.

"features": {
    "App": {
        "status": "_ACTIVE",
        "unavailableReasons": [],
        "modernCapabilities": [{
            "capabilityType": "LOCK_AUTO_REPLY",
            "providerStatuses": [{
                "providerType": "MY_PROVIDER",
                "status": false,
                "unavailableReasons": ["NOT_SUPPORTED_BY_PRODUCT", "DEVICE_OS_NOT_SUPPORTED"]
            }]
        }, 
         ...
         ...             
        {
            "capabilityType": "LOCK_CONTACT_WHITELIST",
            "providerStatuses": [{
                "providerType": "OTHER_PROVIDER",
                "status": true,
                "unavailableReasons": []
            }]
        }
        ]}
 }

    return [MTLValueTransformer transformerWithBlock:^NSDictionary *(NSDictionary *features) {
        NSMutableDictionary *transformedValues = [[NSMutableDictionary alloc] init];
        for (NSString *key in features) {
            id transformedValue = [transformer transformedValue:[features objectForKey:key]];
            if (transformedValue ) {
                [transformedValues setObject:transformedValue forKey:key];
            }
        }

        return transformedValues;
    }];
