I'm experimenting with my first iPad app, a simple Hello World app. The amount of obscure vocabulary, verging on meaningless is like the reading the first few pages of a hardcore science fiction novel. My favourite: I need to create a "provisioning profile", which I partly store in the "portal". The full phrase: "First, create a distribution provisioning profile using iOS Provisioning Portal".
These words and terms are introduced with no definition. One's eyes must glaze over, hoping that the meanings of the terms become clear later.
