Why do the code templates not work for me in Xcode?

Question

I'm having trouble with my source code templates. When I start typing a switch statement, there's no code completion for me. On another machine, this works perfectly. Just not on mine. Actually, typing switch should result in an code completion or template in the form

switch ( xxxxx ) {
case:x
    break;
case:x
    break;
default:
    break
}

or similar. Is there an option in the settings for this kind of stuff? I couldn't find it!
