This last part, UI creation tools might be what you're referring too when you talk about Apple's tools. Xcode gives you a pallet of widgets that you can drag and drop onto your storyboard, setup constraints to help support multiple screens and so on.
Corona does not have a drag and drop system. We can have a long discussion about this on another thread, but we are not planning on adding it.
Back in the 2014/15 time frame, we did make a push to raise awareness about using Corona as a business app. Again in 2016 we produced additional samples for business style and utility apps, but we tend to cater to where most of our usage is which is games. Business apps lean toward native apps and hybrid mobile/html apps. Games tend towards frameworks with high-speed graphic and sprite manipulation.
So while we have created widgets that mimic some of the native widgets, like buttons, switches and sliders, we don't have everything you might want, like a navigation controller. You can certainly create them, but they are not there to be a simple drag and drop or one statement creation of them. Those controls have to live in OpenGL space while your textField and textBox inputs occupy native space and that in itself creates some friction between trying to use them together.
I love Corona. It's the platform I found and fell in love with back in 2011. I'm willing to put in the effort to create the widgets I need for business apps and deal with the quirks of native vs. OpenGL. Most business/utility style apps don't need the OpenGL speed and texture manipulation and something made up of just native or HTML widgets works well for them.
That said, you might want to look at https://github.com/coronalabs-samples
There are several Corona-based non-game examples there.
