Summary:
If you symlink your colorscheme file to ~/Library/Developer/Xcode/UserData/FontAndColorThemes, and then change it in the Xcode UI, Xcode will resolve the symlink, remove it, and copy the file directly instead of editing the file that was symlinked. Having Xcode edit the file directly would be very nice if you want version your theme with git.

Steps to Reproduce:
1. In Xcode's Fonts & Colors preferences, duplicate a colorscheme
2. Move it from `~/Library/Developer/Xcode/UserData/FontAndColorThemes` to your Desktop
3. Quit Xcode
4. Symlink it back with `ln -s ~/Desktop/whatever.xccolortheme ~/Library/Developer/Xcode/UserData/FontAndColorThemes`
5. Re-open Xcode
6. In the Fonts & Colors preferences, change the font size in your theme
7. Quit Xcode
8. Run `ls -la ~/Library/Developer/Xcode/UserData/FontAndColorThemes`

Expected Results:
The `whatever.xccolortheme` in `~/Library/Developer/Xcode/UserData/FontAndColorThemes` is a symlink to the file on your desktop

Actual Results:
Xcode has removed the symlink, and copied the file from your desktop

Version:
Xcode 10.0 beta 3 (10L201y)

Notes:
This also happens with custom `idekeybindings` files in `~/Library/Developer/Xcode/UserData/KeyBindings`
