XCODE Base SDK Missing

Question

I have a application built on IOS 4.1 but recently I have upgraded my XCODE to 3.2.6 which supports IOS 4.3.

How can I run this application in this XCODE. All I am

Answer 1

As well as the Deployment Target, you need to set the Base SDK.

Go to the Project menu, then Edit Project Settings. Select the Build tab, and near the top, there is a Base SDK setting.

Sometimes, you also need to clean all targets, and restart Xcode for it to work properly.

It's also worth keeping the last released version of Xcode, and install the latest beta in a separate folder. (See Can I have multiple Xcode versions installed? for details on how this is done.) Use the beta to test beta features only, and the final for all your other development work.
