I work creating on-demand apps (for Android and iOS). The apps have the same features and only differ in style, which is defined by the clients.
In the case of Android I was able to automate the whole process of creating and submitting apps to the play store. Through Gradle and command lines executed at the / terminal prompt I can generate the .apk and submit it in the play store (A PHP script does everything for me).
Is there any way to do the same thing on iOS?
