In know the question isn't exactly programming related but I think this forum is the best place to ask. So, with risk of the question being pulled, here goes...
What other languages/IDEs are setup as well as the iPhone with Xcode and Interface Builder? Apple uses one design pattern and uses it extremely well - MVC. IB doesn't have any code. It's all UI and that enforces the pattern. By contrast, .NET and Visual Studio fail miserably to separate UI and code. Even XAML with Blend doesn't get any better.
Does any one else (languages/IDEs) do it as well as Apple?
