Since I am new and do not come from the android side.
1) There are some libraries discussed in a subsection and there is documentation for B4I. But:
In what way can I learn the rest? Can I use the android forums?
2) How does the software word. Does B4I translate its code to pure Objective C
1) Modules such as iHttpUtils2 and CustomListView and others are identical to the B4A modules. So the B4A tutorials are relevant.
The documentation for new developers is still lacking. It will be improved.
Please post any question you have. This is how the knowledge base is created.
2) More or less. When you compile your app in release mode it creates a regular Xcode project and compiles it. In debug mode it is much more complicated (you can see that in most cases a full compilation is not required in debug mode).
1) Gestures/ swipes where would I look for that?
2) Tableview has been asked before so I will not put you under pressure but they play a very important part in business apps.
