I use both those for Python, very much enjoy them on iPhone in particular for little UI apps. Equivalent iPad workflow for me had been Swift Playground on iPad and Mac, although it seems stuck about a year ago at Swift 5.10 and iOS 17.5 SDK.

Much slower (minutes) with Xcode Cloud and a git repo, if I can git commit from my iPhone, I can edit app code and commit, watch Xcode Cloud Build see my commit, watch it build with debug logs, and when it works it shows up in TestFlight. Very much not offline, and minutes long loop.
