RLMException', reason: 'Property 'productos' requires a protocol defining the contained type - example: RLMArray

So I am using a Realm for my project, I have an object, 'Pedido' (spanish for order) that has many 'V3Producto' objects, as follows:

@interface V3Producto : RLMObject

@property NSString                  *codeProd; // Este es el código de barras!
@property NSString                  *codigo;
@property NSNumber<RLMDouble>       *descuento;
@property NSString                  *detailProd;
@property NSInteger     idid;
@property NSInteger     idCompania;
@property NSNumber<RLMDouble> *priceProd;
@property NSInteger     stock;

@property int      cantidadComprada;
@property int      cantidad; // cantidad de stock

And the code for the 'Pedidos' (orders)

@interface Pedido : RLMObject

@property NSNumber<RLMDouble>   *idUbicacion;
@property NSString              *fechaPedido;
@property NSString              *sucursal;
@property NSNumber<RLMDouble>   *filterId;
@property RLMArray<V3Producto*>       *productos;

When I run the app, as soon as it loads I get the error: 'RLMException', reason: 'Property 'productos' requires a protocol defining the contained type - example: RLMArray' which is quite strange since, before adding the RLMArray seemed to work just fine! Any V3Producto seems to be a perfectly fine and valid RLMObject! Any ideas?

EDIT: I've tried renaming 'productos' to something else as other threads with the same name suggest but that didn't fix it.

This is because when declaring an RLMArray property, the type must be marked as conforming to a protocol by the same name as the objects it should contain according to Realm Docs

Syntex to declare an RLMArray is :-

RLM_ARRAY_TYPE(ObjectType)
@property RLMArray<ObjectType *><ObjectType> *arrayOfObjectTypes;

Your code should be:-

RLM_ARRAY_TYPE(V3Producto)

@interface Pedido : RLMObject
@property NSNumber <RLMDouble>   *idUbicacion;
@property NSString *fechaPedido;
@property NSString *sucursal;
@property NSNumber <RLMDouble> *filterId;
@property RLMArray <V3Producto*> <V3Producto> *productos;
@end

The proper way to declare a RLMArray, would be as follows:

RLM_ARRAY_TYPE(V3Producto)

@interface Pedido : RLMObject

@property NSNumber<RLMDouble>   *idUbicacion;
...    
@property RLMArray<V3Producto*><V3Producto>       *productosPedido;

Note the I had to declare the type I want to use as an array with a MACRO (in the first line) and the declaration of the array is slightly different (you have to set the type plus the macro you've declared).
