What languages does Xcode 6 Support?

Question

I love Xcode as an IDE. I would like to expand my programming knowledge to include multiple languages, and would like to know which languages are supported in Xcode 6. Obviously Swift, Objective-C, C and C++ can be ran in Xcode. But is there a list of all the languages that you can use with Xcode?

I've been researching like crazy and am very surprised to see that this question hasn't been asked a billion times yet. There are a lot of code specific, "Can I write Perl in Xcode" type of questions, but I have yet to find a list of all the languages I can write using Xcode as my IDE.

According to the Wikipedia page

Xcode supports C, C++, Objective-C, Objective-C++, Java, AppleScript, Python, Ruby, Rez, and Swift source code with a variety of programming models, including but not limited to Cocoa, Carbon, and Java. Third parties have added support for GNU Pascal, Free Pascal, Ada, C#, Perl, and D.
