Really, how to do it? I want to use, for example, Today Extension for my ios app made in unity. When open my app in Xcode and try to do it with File -> New -> Target -> Application Extension -> Today Extension, I get an error about some missing file. Do I need some special way of adding these app extensions or I am doing something fundamentally wrong. Is it still not compatible even though unity did made ios 8.1 build available? Can this be done, or not? Please, give me some answers, because I am wasting my second week on this.
