Well if you think barrier to enter is too high imagine how junior iOS developer used to fight with provisioning profiles, certificates before auto-manage was implemented. How impossible it was/is to test push notifications on iOS as well many other features that require a physical device. A programming language like objective c without Arc with full of retain cycles or memory leaks crashes... the requirement to allocate and deallocae all objects you had. Not a proper interface builder with embedded constrains or auto layout. The list goes to infinity 😀
