Hi,
I installed the iOS 4 SDK yesterday. I previously had the 3.1.2, 3.1.3 and 3.2 SDKs installed. Since installing the iOS 4 SDK, I only have 3.2 and 4.0 available in Xcode. When I load an Xcode project that was targeting an older version (say 3.1.2), it says "Base SDK Missing" in the toolbar.
I've been able to reset the project to target iOS 4 instead - and have successfully built. However, I need to do some ad hoc builds for users who may not have iOS 4 installed on their devices yet. If I give them a build that was done for iOS 4 (not using any iOS 4 features - it's the same code I used to build with 3.1.2), will this execute on their device ok?
Unfortunately I don't have any non-upgraded devices to test this on myself!
Thanks,
John
