I have done some iOS and macOS work in the past using ObjectiveC and C. I have done some DSP work using MaxMSP and PureData.

This morning I decided I wanted to write a simple audio visualizer for my iPhone using SwiftUI, a language and framework I have never used. Within an hour I had through the direction of ChatGPT-4 an app running on my phone using a 3rd party library called AudioKit and drawing some fractal looking thingies, as well as a pretty decent understanding of how it all worked because I asked for detailed explanations of every line of code.

I’m not sure that I could have had this little app up and working in a single day let alone an hour if I only had a search engine at my disposal.
