We're building a web development environment for iPadOS/iOS that hopes to address some of the shortcomings developing iPad-only (and iPhone, but...) Free to download, developer-tools browser built-in (Inspect Browser), Git and PHP available as an in-app purchase. Glad to answer any questions! https://apps.apple.com/us/app/webforge-ide/id6450872424
Having to buy a FOSS VCS as an add on is kind of proving the point that the iPad’s closed software ecosystem is really holding the fantastic hardware back.
It's true iOS software in general has a ways to match desktop capabilities, but desktops also have a bit of a head-start. We do believe iOS can get there, and hopefully exceed it in some ways.
(And in WebForge's case, we not selling just the Git CLI, but a UI and tool integrated into the rest of the IDE, so you're not /just/ paying for access to FOSS software on iPad. And yes, I know VSCode is free on desktops :) )
