To test In-App Purchases I need products, for which I need the app already in iTunes Connect?
Do I understand it right... that I need to create the app in iTunes Connect (including screenshots, icon, description etc.) if I want to start coding & testing the In-App Purchases functionality?
When I click to "Create New In App Purchase" in iTunes Connect, it only lets me pick from my existing apps, but it's for the one I'm currently creating...
(I guess I can submit without finally uploading the binary, I'm just curious if I understand this right.)
