Color Literals not working

I've been looking for information everywhere about this issue and while I've found information about it, it seems that it simply does not work for me. Some of the articles/questions in this forum and others suggest that they should be working, some of them suggest using this method of using:

#colorLiteral(

But it does not render the color picker.

I've updated Xcode to the latest version (13.4.1, as of today), restarted, and nothing seems to work. Can anyone tell me if this is currently working or if there are any other workarounds for this, please? Thanks in advance.
