This error may occurred due to the optional values in your response object try this.... It may works
#property (strong, nonatomic)NSString<Optional> *c;
#property (strong, nonatomic) NSString<Optional> *dt;
#property (strong, nonatomic) NSString<Optional> *cb;
Tip: Please made all properties to Optional
