1`public` should not be there – Khanh TO Feb 10 '16 at 10:48

1Because an interface cannot indeed declare a type. They also can't have access qualifiers. What are you trying to do here? – Jon Hanna Feb 10 '16 at 10:49

and also, `struct` is a keyword and not a type – Grundy Feb 10 '16 at 10:49

1You can find more information here on SO http://stackoverflow.com/questions/15009073/interfaces-cannot-declare-types. Aside you can solve this by using an abstract class instead. – dryman Feb 10 '16 at 10:49
