@Almaz5200 would you like to try it before I merge it? I would like to make sure that it works as expected.

@wojciech-kulik thank you for the invite! I've tried it and it works, and gives me an improvement consistent with the tests we did previously. However I do have some security concerns about this feature. In this current version any other program can just do ~/.local/share/nvim/lazy/xcodebuild.nvim/tools/xcodebuild_offline some_evil_stuff. And even if you remove sudo from line 29, wouldn't it be possible to modify this file in any malicious way from outside, do whatever you want and change it back?

Also for some reason visudo command makes my tmux crash, I only was able to run it from a plain terminal session

@Almaz5200 I finished :). You can check the code & docs one more time 🙏

Looks great to me!
I thought in might be possible to inject something in the xcodebuild so that it expands to something like xcodebuild "-help"; some_bad_things "", but I was not able to do so, it seems "" escapes everything well.

So everything looks safe now, and the wiki describes the seriousness of it appropriately :D
Thank you for such a quick collaboration! 🍻 :)
