Do i need to use Xcode or Eclipse to submit a game i created in Unity or it can go directly to appstore?

Let say i have created a game in unity and would like to submit the game in iOS or Android google store. Do i need to use Xcode/Eclipse in order to submit my game to the respective appstore or can it go directly from unity to appstore. I believe with all the tutorials available on unity, it would be easier to learn programming in unity but i doubt that on Xcode or Eclipse. that is why i would like to ignore them totally what if i need to set up in app purchases, allow ads or debug the game, can these still be done without xcode& Eclipse someone please let me know Thanks
