No such module 'Orion' - Fix

While building NeonKeys, my upcoming iOS keyboard customization tweak, I encountered a problem where Xcode was erroring "No such module 'Orion'". make do still worked, it was just Xcode.

This error occurred after I transferred the project from my MacBook over to my Hackintosh directly (by just copying over the files, no git). And the error was related to some cache files. Mainly the file inside .theos directory named .spm_config. To fix the error run these commands inside your project:

rm -rf .theos .spm
make clean
make spm

Re-open Xcode (important!). The error should be gone and should no longer bother you.
