Storyboard gives an internal error

I'm using XCode 9.2 on macOS 10.12.6 (Sierra)
So, XCode was working fine and the assets in storyboard load, like the textbox you can drag into the storyboard. I'm using a Single View Application. Until I wanted to free up some storage by deleting some XCode files under "Developer". Since this, the assets like the textbox you can drag into the storyboard don't load. To be a little more descriptive, it does function properly, but the texture for it doesn't load. And clicking on Storyboard gives me an "An internal error has occurred, your editing may be limited" message. Something along those lines. It loads perfectly fine in the simulator. How can I fix this?
I've tried
- Deleting everything associated with XCode, including the .xip and application
- Reinstalling
- Finding similar issues
Can't find anything. The object shows it's hitbox but has no texture.

Does it work correctly when running the app ?


What happens with a brand new project ?

1. Yes, it works great and fine when running the app.
2. Same with a brand new project, missing texture/asset on certain buttons.
I've deleted XCode, but if you want me to, I can show a screenshot since reinstalling it did not fix it.

No need to see it, I imagine what you get.


You should try reinstall again and accept to install the tools when proposed.

XCode doesn't give me a prompt to install the command Line tools, but on previous occasions I did get it and pressed the "not now" option.

I do not know enough the internal working of XCode to be sure, but I would suspect it.
