Having said that, a lot of software developers -- including Panic -- have not had great experiences trying to sell development tools on iOS. It feels like there should be a big enough market for this, but it's unclear there's actually much of one. If Apple brought Xcode to iPadOS it would likely require changes to the OS to support that kind of development toolchain, and that would make it easier for other companies to bring their tools, both commercial and free. But I half-suspect the official Apple answer to "when are you gonna let us develop on iPadOS" will be "may we interest you in this Apple Silicon-based, touch screen MacBook that natively runs iPad apps."
The iPad is a computer with a keyboard and mouse and a full-featured web browser. There are also language-specific native IDEs like Pythonista and Play.js. There are Git clients available natively as well. Pretty much the only thing you can’t do is make iPad apps on the iPad, which is a pretty small subset of programmers. Pythonista costs $10 and has nearly 1k reviews, so someone must be using it.
So why do people constantly ask “does anyone really want to develop on a computer that offers many development options?” The answer is yes, of course people seriously want to develop on an iPad.
If I could Handoff something like a shallow clone of a git repo and its working index between iPad and mac, I'd be in love.
