To be completely honest I haven't been involved in the Windows ecosystem in probably 15 years so I am not really sure. I switched over to using Macs in 2005 or so. I just Googled it and poked around and, yeah, at a high level it looks a lot like the old VB form builder.
The thing is, the form builder was just part of what made the VB experience so great. It was how everything tied together conceptually into a complete environment that, crucially, was very easy to understand and very approachable. The form builder was easy to grasp, language was very simple and straightforward, and the documentation was just astounding (to this day I have yet to find anyone who has as good documentation as Microsoft did in the 90s.) You could crank out a simple app in a matter of hours with it.
In the late 90s I got swept up in the dot-com boom and started doing web development. That's been my primary bread and butter since, although these days I have moved into a more management-focused role so most of the development I do is on my own time to keep my skills sharp. I have occasionally written things in Java (using Netbeans, whose form builder was very similar to VB) and Objective-C (again, Interface Builder reminded me a lot of VB).
I've been doing a lot of Swift recently for macOS development because it's such a fun language, but I haven't jumped over to using SwiftUI. It's just not ready for prime time yet, IMHO, especially for macOS apps. And I really just prefer building GUIs using a GUI builder like Storyboards or even old fashioned NIBs/XIBs, since most of the macOS apps I write I am the sole developer on, the version control issues with GUI definition files aren't a big issue for me.
Though I will say that I think SwiftUI has potential - especially with the live preview as you're building. It just doesn't work very well right now for complex macOS apps.
What are your thoughts about winforms? Seems pretty similar, no?
