How to make Xcode recognize a custom file extension as Objective-C for syntax highlighting?

Question

I\'d like to get Xcode 4 to recognize a custom file extension (e.g. *.lx) as Objective-C for syntax highlighting and indentation purposes. How do I get the tool to automatically

Answer 1

In Xcode when your file is active in the editor, you go to the Editor Menu -> Syntax Coloring -> Objective-C

This will apply objective-c syntax coloring to a file. Worked for me with a plain text file regardless of its extension.

This seemed to work for automatic indentation also
