This is helpful overall but perhaps your Xcode experience is out of date, or at least several of your comments don’t match my experience of Xcode 12.5.

> The actual code editing part is just a text editor, e.g. searching for function calls involves using the search function, as opposed to a keyboard shortcut that uses static code analysis.

Xcode has indexed static analysis, symbol navigation, jump to definition, quick fixes, in-line quick help and a bunch of other features I use every day that lift it out of the ‘just a text editor’ class.

> Most warnings for your code won't show up until you try to build it, therefore the feedback loop is extremely slow.

This hasn’t been my experience - warnings that appear on build generally also appear when saving a file. There’s no need to trigger a build to get feeedback.

> Code refactoring features do not exist on Xcode.

Editor > Refactor reveals 13 refactoring options for me in Xcode 12.5.

I like Xcode, even as someone who switches between it and JetBrains editors (for frontend/backend work) every week. The only thing I really miss is stable vim emulation.
