“Base SDK Missing” after upgrading to Xcode 3.2.5

Question

So I took the step upgrading to Xcode 3.2.5 (iPhone SDK 4.2) and now I cannot run to device. I always see this now in the dev environment:

Answer 1

I solved this problem, by doing this:

Project->Edit Project Settings->Build->Base SDK->Latest SDK (4.2)
Project->Edit Project Settings->Build->iOS Target Deployment->iOS 4.2

Project->Edit Active Target (myTarget)->Base SDK->Latest SDK (4.2)
Project->Edit Active Target (myTarget)->iOS Target Deployment->iOS 4.2

And, If you still have problems:

Click the box that says base SDK missing, and select:

Simulator -> Debug

That should do it.
