Thanks Alexander,

I saw that and now I know for certain.  Have a nice day.

Fair enough, could you tell me which languages are supposed to have code completion, because CSS doesn't even work anymore?
Display Recorder hasn't been updated for iOS 6 yet, so the screencast will have to wait. I do however know of one programming language that doesn't work with code completion, C#

I have tried to get if, for, foreach, etc to work, but they have to be typed in manually.
Has it ever been done in any other iOS app, to your knowledge?
I noticed this as well. I was typing Hello World and I did the following:

1. Undo 1x
2. Redo 1x
3. Undo 2x
4. Expanded the left sidebar and lost the undo/redo history completely.
