Spent the weekend using Claude to code an app. Started out as a web app which was much easier to concept together, and then converted it to a classic Mac app with RealBasic 5. Claude was really helpful in troubleshooting all the reasons different parts didn’t work, besides my complete lack of experience that is. 😁

I’m still working on the graphics, but I’m pretty happy so far.

  • Week view
  • Favoriting a city which it does by saving a text file in the app folder
  • Dark mode
Here it is on my Duo 2300:

This is neat! 😀

Does it provide the weather for all cities or specifically those in the U.S. at the moment?
Right now it’s pulling weather from a list of 60 major us cities based on their lon and lat. Even still there is a 1 or 2 second lag on my Duo reading a list of 60 that I didn’t feel in sheepshaver where I built it. Thats one of the things I want to improve in it.

To deal with SSL, which System 8/9 cant really deal with I have a php hosted that reads an https api and provides an http link my Powerbook can deal with. There was a lot of setup and bug fixing in the php because it reads and serves up the weather data in the hourly/daily slots the app uses.

This gets better and better. 🙂

Do you plan to share it with the community at some point? I'd love the chance to be able to play around with it.
 
By what process does claude vibe code in RealBasic on classic MacOS?

I can’t quite guess.

I’m not using Claude in an agentic sense so I think the process is the same, regardless of which app you’re coding in. I planned out the structure, features, and UX of the app; Claude figured out the code and where in the app to place it. The smoothness and “trial and error“ nature of programming for the twenty year old LOL RealBasic 5 it was probably exacerbated by if not being as familiar with the IDE as it would say Xcode. This has been especially apparent as I’ve been de-bugging problems that arise.

One thing I’ll say, is that the very very first version of this app I did as a web app which was significantly quicker to build a prototype on because all the codes lived in a single page, well two if you count the PHP, as opposed to having to place the code in all kinds of methods, events, and screen drawing sections.

When I encountered weird forecasting issues, Claude was very good at looking at the raw API browser output, and figuring out what issues were arising.

A cool end-result has been that I now know enough about programming in real basic to make edits and add small features myself without having to rely on Claude.
