I managed to include AVS in my iOS application, login with amazon, listening to user say things like "whats the weather?" and getting a proper response.
I also have a custom skill, say invocation "mySkill"
My next step is calling my custom skill from my iOS application instead of standard alexa skills. But I want to know if I can restrict usage ONLY TO my custom skills? I do not want users to get response from other skills and then "suggest" my app gave them the response, since I cannot control what skill they invoke. I want them to be only able to access "mySkill"
