Xcode Purge

Sometimes you just have to purge. With Xcode, it helps to completely blow away the Derived Data and SPM Cache directories. These directories contain all of the build artifacts produced by Xcode and resolved Swift packages. When a clean action does not completely reset your build it is time to purge.

These 2 functions can be added to your shell so you can simply run xcpurge to send Derived Data and SPM Cache to your Trash. You can recover it if necessary.

Usage

You likely are now using zsh with macOS and so you can update ~/.zshrc to define these functions. What I recommend is creating a folder at ~/.shell and create a file named ~/.shell/functions in that folder. Add the functions below to this file. Make sure to also run chmod u+x ~/.shell/functions and then add source $HOME/.shell/functions to ~/.zshrc so your shell has these functions defined. You can then run xcpurge or trash like any other command. The first time you run it you will need to grant permission since i

ZSH CheatSheet

This is a cheat sheet for how to perform various actions to ZSH, which can be tricky to find on the web as the syntax is not intuitive and it is generally not very well-documented.

Strings

Description	Syntax
Get the length of a string	`${#VARNAME}`
Get a single character	`${VARNAME[index]}`

Edit Feb 4 5:16 PM: Skip to the bottom if you just want the article

It has been brought to my attention that rehosting someone else's content without asking them — even if you link to the original content — is not exactly polite. I did not ask the author before I rehosted his article, and while I feel I should have known better than to that, it just didn't occurr to me. It's not exactly plagarism, but it's still wrong on some level. I have reached out to him now about hosting it here publically, and if he says it's alright, I'll put it back.

You can find the original article here, on his site, and on his Medium page.
