XCode autocompletion: Is it possible to suggest "NSString" when I typed "NSS"?

Question

XCode suggest me "NSSet" when I typed "NSS". It is not very good for me. I use NSString quite often.
Is it possible to suggest "NSString" when I typed "NSS"?

Answer 1

Type NSString into the editor, select that and drag it with your mouse to Code Snippet Library (⌃⌥⌘2 if not open), then set its completion shortcut to something not used by Xcode, like "foo".

Now every time you want to use NSString just type foo and Xcode will offer to auto-complete with NSString. It requires some time to get used to typing something else just like with macro Srikar suggested, but it doesn't add anything new to code itself.
